* Refactored RemoteFragment and created a compound view for the
actual remote. I called it ControlPad to make it more clear what
its main function is.
* Implemented a custom grid layout (SquareGridLayout) that will
always be square. When its width and height are both set to
match_parent, it will take the smallest of the two as the
actual size.
* For devices with a smallest width smaller then 360dp the ControlPad
is sized to the maximum available space. For larger devices we still
use the old fixed sizes.
