* Add restart TypeScript Server logic
**bug**
Currently, we often have to reload VSCode when we need to restart the TSserver to enable logging or change typescript versions
**Fix**
Add a way to restart the TSServer
* Remove old command
* Formatting
* Handle typesInstallerInitializationFailed
Display a warning message when the ts typings installer fails to initilize. One possible cause is that npm is not installed
* Fix a spell
* Add new option to disable/enable jsdoc autocompletion
* Refactor JsDocCompletionItem
- remove internal command
- move TS service call and template generation to CompletionItem
- only call TS service if JSDoc completion is enabled in settings
- add local config and config update method to CompletionProvider
* Change how and when JsDocCompletionHelper is registered
Register JsDocCompletionHelper and update configuration in registerProviders instead of activate. Also react to configuration change.
* Rename JsDocCompletionHelper to JsDocCompletionProvider
* Add missing newline at the eof
* Restore completion prompt for JSDoc autocomplete
Restores internal command but but as a separate class. Registers command on extension activation.
* Add TSServer Log Options
Adds support for collecting the TSServer log directly in VS Code
* Add enable logging option
* Handle case where user is on older version of TS
* Rename
* Activate on openTSServerLog command
* VSCode -> VS Code
* Use common TS install for both the TS Extension and Html Extension
**Bug**
At least two version of Typescript are shipped in our extensions: one in the typescript extension and one for the html extension. This adds about 5MB to package install size and also results in inconsistent behavior
**Fix**
Change the TypeScript extension to also use the common version of TypeScript. Bump this version up to 2.2.1
* Don't hardcode paths for typescript
* Prototype of Implementations Code Lens Provider for TypeScript
Adds a prototype code lens that shows the number of implementations for interfaces and abstract classes. This shares a lot of code with the references code lens provider, so I extracted most of the common stuff into a base class.
* Support children of interfaces
* Add setting to control implementations code lens
