* In the small view, show the action buttons when hovering anywhere over the cell
This matches the previous behavior.
* Explicitly hide/show the priority icon in the stack view
* Restore right padding on the compact view's stack view
* style fixes
Converted TorrentTableView from older style cell based table to more modern view based
* floating group rows are now used for an improved groups experience
* individual group indicators are hidden when _Use Groups_ is selected to minimize visual clutter (see #3328 )
* removed negated `usesAlternatingRowBackgroundColors` flag for minimal view in Controller.mm (personal preference - easy to restore)
