- 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. SVN r932 (trunk)
