Big SVN Update

Okay, lots of new stuff in the environment repo. Some had export errors about the textures not being able to be embedded, in which case I included the texture in the corresponding folder. Included in the update; Biodome, bad guy biodomes, planeteer research facility number one, and both team's power units. Enjoy, let me know of any problems. I hope they look good in engine. Let me know. Also, land should be done in the next week and a half two weeks max. This timeframe a problem?
