For a change here's a build that is just pure CVS with no additions from me.

Nothing shockingly new but there are a few bug-fixes from the SCP team in there.
FS2_OpenFRED2_Open*What's new** All the stuff which wasn't yet in CVS from the May 9th build
* All the stuff from Taylor's env-mapping builds
* Missing backgrounds in FRED - Fixed
* Untargetable systems are actually targetable - Fixed
* All player ships flagged as Targetable as bomb - Fixed
* Invulnerability flag set for seemingly random ships - Fixed
Anyone who has saved a mission using FRED builds after late February which contain one or more invulnerable ships should check their missions to see if the correct ship is still invulnerable. The targetable as bomb thing was never going to affect anyone in single player anyway but might be annoying to anyone making multiplayer missions.
