0.3 material testing system

I got all the common material types working into the testing system, and got the camera controls working so the materials could be more accurately checked. Not much else was added to the tester. I attempted to get another bug to work on, but the ones listed were either already taken or seemed like to large of bugs to pick up at this one. I'll leave ccliffe a message in hopes he can get me some more work to do. I feel the work done in this tester wasn't good enough to account for 0.3, so I guess my only option is to do an extra amount of work for 0.4 to make up for this.
