Fix camera.
Put basic ground, water and house into game.
Merge branch 'master' of git@github.com:fierydrake/fishinggirl.git

Conflicts:
	src/com/sammik/fishinggirl/FishingGirlGame.java
Added asset manager (should probably use the one in libgdx)
Added a bunch of assets (cliff, water, etc)
Added GameObject based on Sprite
Probably some stuff still to convert to using GameObject code
Forgot to add some files in last commit
