* Add a drag indicator at the top
* Fix flex layout wrapping when buttons didn't fit on a single line
* Fix BottomSheetDialog peek height too small on landscape orientation
* General cleanup of the layout
Aligning the buttons to the bottom of the game image was determined to look odd due to the amount of padding between the title and buttons. They are now back to being below the title but the buttons have been resized with "Play" being a wide button while "Pin" has been replaced with Google Material Icons's "Add To Home Screen" icon and sized down to an icon-only button.
This commit focuses on making the UI completely usable using a controller so that a user won't have to switch between their device's touch screen and a controller constantly.
This commit makes a few improvements to the UI/UX:
* Crop Game Icons to ImageView
* Controller Support for Game List
* EmulationActivity is fullscreen now
This commit refactors `AppDialog` by bringing it in line with the guidelines. In addition, it improves the design of it substantially by modifying the layout and making it a `BottomSheetDialogFragment`.
