[Bf-committers] New patch allows frame skipping for armature ghosting

Heh! I first wanted to get feedback on the usability of the feature.  
And then there was no real space for the button itself (You also  
squeeze it a bit). And it requires a proper version patch on fileread  
to prevent the step size to become zero. And an initialize.

BTW; can you make the patch using "cvs diff -u" ? I never apply patches  
before reading it carefully, and that gives more readable diffs. I'm  
also curious why you decided to make the step go in 0.5 frames... if  
you want precise control, it could become a float too?
