suggestion : add challenge/download/currency system, would rox

Hi i been lurking around the IBp sites and checking out their
system and games, and i must admit they got some pretty sweet
features in the arcade system..

features i would like to see for vb-ibp arcade would be :

- Challenge system
- Download botton on games (enable/disable in adminCP)
- Currency enabled, so you can use/win Casino|dollers/vbexperience
so perhaps some games cost X ammount to play beating the high score
earns you X ammount times x1.

But really happy about the mod in general and glad i dont have all those
bugs i see man others have,.

Cheers good work, :up: :up: :up: :up: :up:
