- Fixed: Wall drawing handled fixed light levels improperly (but did not

completely ignore them, either).
- Separated light level fixing out of player_t's fixedcolormap parameter.
  Using a fixed light level (e.g. PowerTorch) will no longer wipe out
  colored lighting.
- Moved the blending rectangle drawing into a separate discrete stage, since
  doing it while copying the 3D view window to the display now blends
  underneath the weapon instead of on top of it.
- Consolidated the special colormaps into a single 2D table.
- Tweaked the special colormaps slightly to make the true color results more
  closely match the paletted approximations.
- fb_d3d9_shaders.h was getting unwieldy, so I moved the shaders out of the
  executable and into zdoom.pk3. Shaders are still precompiled so I don't need
  to pull in a dependancy on D3DX.
- Added a few more shaders to accomodate drawing weapons with all the in-game
  lighting models. These are accessed with the new DrawTexture tags
  DTA_SpecialColormap and DTA_ColormapStyle.
- Player weapon sprites are now drawn using Direct3D and receive all the
  benefits thereof.
