[java] Colourama (new version)

Hi I just uploaded a new version of Colourama... not many gameplay changes, though... simply added a purpose (you need to reach a certain score to move on to the next level until you reach the end). I did some massive graphical changes, though, to see if people think it''s more appealing now (the first-look opinion wasn''t being very positive)... let me know what you think about it.
