Merge remote-tracking branch 'origin/master' into chris
Added a lot of empty functions and not fully used variables for the checkpoint
FIXED
Block Draw works much better and is easier to work with
Progress on Collapsing/stability made and turn taking (largely untested).
bugfixes, draw now functions properly
collapsing animation works? (for 1 block stacks)
Bundled up redundant code into setup() and fixed PlayerTurn logic. Created pop-ups for how-to, whose turn it is, and new round which are called through GameView. Fixed the GameActivity layout so that it displays best on all screen sizes.
