Created BalloonGame.js and added a button to access it.
Two images that didn't seem to get commited last time.
Moved the balloon game button function to garden state.

Also the three images that didn't get uploaded before I'm trying to
upload once again. The code in BalloonGame.js is likely to be temporary,
me just trying out different things. So no need to go through it just
yet.
Added audio assets
Worked on Bird Hero Intro
Changed how buttons are created
Changed buttons again, more flexible

You are now able to use several representations on the same button.
Updated to Phaser from dev branch
Birdhero: Make it rain!
Use new cover object in other places
