- Added translucent blending modes to FMultipatchTexture (not tested yet!)

- Also changed all true color texture creation functions to use proper alpha
  values instead of inverted ones.
- Changed FRemapTable so that all palette entries must contain proper alpha
  values. 
- Fixed: The F1 screen check in m_menu.cpp was missing a NULL pointer check.
- Changed: The boss brain's explosions play weapons/rocklx which is an 
  unlimited sound. This can become extremely loud. Replaced with a new
  sound which is just an alias to weapons/rocklx but has a limit of 4.
