- Added tracking of time spent specifically in running action functions. I feel kind of stupid

about this now. I spent three days trying to figure out why the VC++ debug version was so slow.
  It turns out I had a conditional breakpoint set in a high-traffic area. D'oh!

The rest of this stuff should get merged into trunk:

- Fixed: Writing to debugfile uses the standard fprintf, which does not understand %td on VC++.
- Fixed: Instead of crashing when a sprite has been scaled to 0, just don't draw it.
