Subject: Lots of updates

* Networking is finally working
* Started moveing physics into the shared domain
* Streams now have a readString() and writeString() method
* streams are passed to the lua context for networking
* Refactored cameras and physboxes to use metatables
* Finally wrote the pushvector3* and popvector3* methods
* Fixed a few crashes in ;main
* Deleted a lot of code
