Proxy derive macros, rustc plugin codegen, safety improvements (#67)

* adds LuaProxy derive macro
* bevy_api_gen is now a rustc extension which can work on arbitrary codebases
* removed some unsafe blocks
* all wrappers are now Clone regardless if the underlying type is due to Arc
* added high level documentation
