- Texture animation improvements:

* Animations are now millisecond-accurate, so delays in ANIMDEFS can have
    fractional parts.
  * Cleaned up the animation code and moved it into r_anim.cpp.
  * Blood's oscillating texture animations are now available for use by actual
    supported games by adding the word "oscillate" after a "range" definition
    in ANIMDEFS.
  * Not exactly texture animation, but it's handled in the same function as
    texture animations: Scrolling skies also have millisecond precision.
