Changelog for v0.01.02

Features:

Steam Cloud support: You no longer have to unlock everything again on each machine you play on! 
NB: The first machine you play on with the update will sync it's existing progress to steam cloud. After that other machines you play on will take the progress that's in the cloud. (So play on the machine with the most progress first!) 
Added direction control calibration (up/down/left/right). You should be able calibrate and use "retro" controllers and arcade sticks now. 
Keyboard can now be set up to have multiple players. Choose Keyboard Setup in the options menu to set your keys. 
You can now use the mouse to navigate the front menus.
