Add Partial Implementation of style DOM traits for Gecko, and some basic glue to let Gecko call into Servo

The wrapper stuff is partially-complete, modulo some unimplemented methods. The glue code is just a toy for now. Regardless, I think it's worth getting some of this stuff in-tree to minimize breakage.
