The entire layout is now selectable for grid items rather than just the card, this greatly increases the visibility of the selection when not in touch mode as the contrast of a darken effect on the icon can be minimal depending on how dark the icon already is.
* Make sure icons have a 1:1 ratio
* Use recyclerview padding to increase grid edge margins
* Fix race condition in searching roms
* Use notify insert for adapter
This commit makes a few improvements to the UI/UX:
* Crop Game Icons to ImageView
* Controller Support for Game List
* EmulationActivity is fullscreen now
With `RecyclerView` being used rather than `ListView` or `GridView`. It's now possible to display the items in a flexible manner and so support for a grid view in addition to the already existing list view was added in.
