Scenegraph branch

[thelusiv]

I've updated a few things in the scenegraph branch...I modified the logging classes a little to remove the dependence on shared pointers, and then set up a few basic logs using it. They don't seem to be working yet, perhaps it's because of my modifications...

I also set up the control class write function to use the configfile format instead of the old format. I haven't rewritten the read function yet, just because I want to first make sure the game will figure out if the new file exists, and if it doesn't, try to fall back to the old format. This way everyone won't have to re-input all their controls, but the game will always write in the new format, so they'll be automatically upgraded.
