[pygame] FastRenderGroup (update 3)

[DR0ID <dr0id@xxxxxxxxxx>]

Hello again


Here comes Version v1.1.72 of the FastRenderGroup!
Download: 
http://www.mypage.bluewin.ch/DR0ID/pygame_projects.html#fast_dirty1

Changes:

-Layersystem is now in a separated LayeredRenderGroup (you can use that 
with the old pygame.sprite.Sprites)
-it comes with an unittest class for the LayeredRenderGroup and is 
therefor working
-FastRenderGroup now works only with the DirtySprite, but I'm open to 
suggestions if it should be compatible or not with the old 
pygame.sprite.Sprites and how to do it



Please take a look and i would appreciate some feedback. Sorry for the 
delay, but now it is here :-)


Thanks

~DR0ID
