INFOCOMMIT: update gitignore for android, rm gen/ and weird gitignore

player coordinates set in player.destination are not handled in the
right coord sys; need to read up on how that stuff works from
https://code.google.com/p/libgdx-users/wiki/Camera before continuing
debugging/development.

player will now move based on input
enemies now appear on screen
enemies now spawn with correct delay
pause button now has 100ms delay associated with it

consider merging this old bugfix branch back to dev/master and
rebranching?
