- Got rid of most TexMan.AddPatch calls because they are no longer needed.

- Got rid of R_InitPatches because the new texture init code needs to preload
  everything to work correctly.
- Rewrote texture manager initialization to order textures primarily by WAD 
  rather than by type. This way later textures will always override earlier 
  ones. The only exception is that TEX_MiscPatch are only used as a fallback
  if nothing else can be found.
- Optimized the tryany case of FTextureManager::CheckForTexture. It is not
  necessary to scan the hash chain twice. The required information can be
  retrieved during the first pass as easily and even offers a little more
  control.
- Made FFont destructor virtual.
- Added 'Ice' translation to DECORATE.

(Caution: Not fully tested yet!)
