[Caisses] v1.2 : Undo/redo, menu saving, etc...

Caisses is one of the most download games here, and people have requested some features for a while. I had been too lazy to add them, but decided to do it now !

So here comes version 1.2 with a few nice things :
- Added 10 000 levels of undo/redo !! Hope that'll be enough
- Reworked the interface a little to have the undo/redo buttons fit on the screen
- Bigger exit button
- Fixed levels 104 and 130
- Code cleaning
- Raster can now be turned off !
- Now saves menu level !
- Added version number in case I update again someday ^^

I really hope you'll like it ! If you see anything fishy (I didn't spend too much time testing), feel free to tell me !

This version works on both PocketPC and Smartphones
