[OLPC-Games] XOBall - new game

[Prosenc Robert]

hi all.

just added XOBall to olpc.at wiki  ( http://www.olpcaustria.org/mediawiki/index.php/XoBall 
  ) .

XOBall is a jump'n'run game, written with pygame using a realtime  
physics engine called Chipmunk...
it still needs to be converted into an activity - any help is  
welcome ;-)

also, there is still lots of need for additional content in the game,  
as well as levels using it...

the wiki-page has links to all sources, including an epidoc generated  
html-documentation (plus a pdf version), as well as recent uml-diagrams.

i tried to document the code diligently...

hope you like it.

greets, rob.
