As described in #998, images are sometimes displayed with an incorrect
orientation. This is because cameras often write files in the native sensor byte
order and attach the `Orientation` EXIF metadata to tell end-user devices how to
display the images based on the original author’s capture orientation.
Electron/Chromium (and therefore Signal Desktop) currently doesn’t support
applying this metadata for `<img>` tags, e.g. CSS `image-orientation: from-
image`. As a workaround, this change uses the `loadImage` library with the
`orientation: true` flag to auto-orient images ~~before display~~ upon receipt
and before sending.
**Changes**
- [x] ~~Auto-orient images during display in message list view~~
- [x] Ensure image is not displayed until loaded (to prevent layout reflow) .
- [x] Auto-orient images upon receipt and before storing in IndexedDB
(~~or preserve original data until Chromium offers native fix?~~)
- [x] Auto-orient images in compose area preview.
- [x] ~~Auto-orient images in lightbox view~~
- [x] Auto-orient images before sending / storage.
- [x] Add EditorConfig for sharing code styles across editors.
- [x] Fix ESLint ignore file.
- [x] Change `function-paren-newline` ESLint rule from
`consistent` to `multiline`.
- [x] Add `operator-linebreak` ESLint rule for consistency.
- [x] Added `blob-util` dependency for converting between array buffers,
blobs, etc.
- [x] Extracted `createMessageHandler` to consolidate logic for
`onMessageReceived` and `onSentMessage`.
- [x] Introduce `async` / `await` to simplify async coding (restore control flow
for branching, loops, and exceptions).
- [x] Introduce `window.Signal` namespace for exposing ES2015+ CommonJS modules.
- [x] Introduce rudimentary `Message` and `Attachment` types to begin defining a
schema and versioning. This will allow us to track which changes, e.g.
auto-orient JPEGs, per message / attachment as well as which fields
are stored.
- [x] Renamed `window.dataURLtoBlob` to `window.dataURLToBlobSync` to both fix
the strange `camelCase` as well as to highlight that this operation is
synchronous and therefore blocks the user thread.
- [x] Normalize all JPEG MIME types to `image/jpeg`, eliminating the
invalid `image/jpg`.
- [x] Add `npm run test-modules` command for testing non-browser specific
CommonJS modules.
- **Stretch Goals**
- [ ] ~~Restrict `autoOrientImage` to `Blob` to narrow API interface.~~ Do
this once we use PureScript.
- [ ] ~~Return non-JPEGs as no-op from `autoOrientImage`.~~ Skipping
`autoOrientImage` for non-JPEGs altogether.
- [ ] Retroactively auto-orient existing JPEG image attachments in the
background.

Implement attachment process version
Instead of keeping track of last normalization (processing) date, we now
keep track of an internal processing version that will help us understand
what kind of processing has already been completed for a given attachment.
This will let us retroactively upgrade existing attachments.
As we add more processing steps, we can build a processing pipeline that can
convert any attachment processing version into a higher one,
e.g. 4 -> 5 -> 6 -> 7.

Add `autoOrientImage` module
This module exposes `loadImage` with a `Promise` based interface and pre-
populates `orientation: true` option to auto-orient input. Returns data URL
as string.
The module uses a named export as refactoring references of modules with
`default` (`module.exports`) export references can be error-prone.

TODO: Use native `Canvas::toBlob`
One challenge is that `Canvas::toBlob` is async whereas
`dataURLtoBlob` is sync.

Use `Canvas::toDataURL` to preserve `ImageView` logic
This way, all the other code paths remain untouched in case we want to
remove the auto-orient code once Chrome supports the `image-orientation`
CSS property.

Remove `blueimp-load-image` Bower dependency
Add names and sizes for all attachments except images, and (as with
arbitrary attachments), clicking on the text will open a save dialog.
In the absence of a filename, choose something that makes sense.
Display different icons for different media types, including distinct icons
for voice notes and audio files.
In iOS theme, audio, video, voice, and files are all encapsulated in bubbles.

Sometimes .mov files arrive with content type video/quicktime, but must
be saved to .mov in order for osx to recognize them as videos and open
the appropriate default program, display thumbnails, etc...
// FREEBIE
Make arbitrary files look nicer and display the filename.
If an audio or video element fails to load for any reason, timeout after
a few seconds and render it as an arbitrary file. Also short circuit to
this treatment for common audio and video file types that we know are
going to fail, e.g., proprietary formats from apple.
// FREEBIE
Despite the "click to save"-description of unsupported file types, clicking them did not save them.
This commit implements a Save-As dialog instead of opening the file in chrome.
// FREEBIE
Messages with images or media were causing the scroll position to jump
around when they loaded, because rendering them changed the height of their
elements from 0 to full-height sometime after they were inserted into
the DOM.
Now when rendering attachments, we wait for them to load so they can
render at full height immediately, then warn our parent message list
before and after a potential height change, so the scroll position can
be saved and reset.
// FREEBIE
Bind the sub-view to some data when we initialize it, rather than
passing it in on render. That means the image view click handler will
only ever open the blob we bound it to, even if its src attr changes for
some reason, which should never happen, but if it does, it's nice to
guard against opening arbitrary urls found in the dom.
// FREEBIE
Images that are attached to messages, either sent or received
can be opened in a new tab by clicking on them.
The previous approach that used Anchors to open the image
attachmets failed in various systems because:
- Chrome on Windows recognised "blob" as protocol and tried
to find an app for it
- Chromium on Ubuntu didn't open a new window to load the URL
The new approach adds a "click" listener to the IMG element and
opens the link using window.open (which seems to be working globaly).
Resolves: #252
Converting attachment data to base64-encoded data uris takes O(n) and
there's no need! URL.createObjectURL returns a magic link that can be
set as the `src` attribute to `img`, `video`, and `audio` tags to load
blob data directly without copying.
