Looks terrible but client inputs->server calc->sending state back to client is working now. Gonna have to calculate the wheel movement on the client though. Way too glitchy when sent at 30fps from server as it is now. Wheels are freaking out.
Moved all assets in "Third Party" into "Plugins" instead. Code in "Plugins" or "Standard Assets" folders does not get recompiled every time, which can save some time. Sort of a poor man's DLL. Note that code in Standard Assets/Plugins can only communicate one-way though: Other code can see it, but it can't see out.
