Tweaking textures only.

Removed duplicate files

Some texture updates. Experimenting with GIMP creating Normal maps and Specular Maps manually. Also updated maps to the correct Specular power in the TRN file to match stock map settings.

Minor update. Removed assault depot from being built by the constructor and moved it to the utility cons. Increased scrap dropped from rocket towers.

Fixed the thug recycler cons to build the correct armory. Fixed the main commander cons to build the correct Supply Depot to unlock the rest of the heavy sabres.

While trying to fix the MPICheck file and adding the missing GH assets, I overwrote files allowing the player and thugs to build units and buildings. I've hopefully fixed that and renabled the build tree for the Commander and Thug Recycler Commanders. The Heavy Warrior should also hopefully be fixed.

Added more missing Greenheart assets and material files.

Updated asset checking file. Added missing Greenheart msh's.

Updated MPICheck file to prevent SPAM error warnings in the console. I'm sure there are more I need to add.
