Entity Implementations

Instead of using the native entities we're  best off re-implementing them in c#. 

It feels like we have an opportunity here, starting fresh, to delete and clean everything up, to make things make a bit more sense.

I don't think Valve have that luxury, I'm guessing they have to support demos, saves and maps from 10 years ago, they can't just fuck it all off.

So this month as a first step I converted doors, buttons and a light entity to c#. 

This uncovered more stuff that I'd like to reimplement in c#. The native code has a MOVETYPE_PUSH system where entities (like doors) move and but push entities. They can kill entities that block their way etc.

It's a system we need because we don't really want to make things like the player/npc controllers purely physics based. But I also think it's a system that we're best off implementing in c# so we can manipulate it a bit easier.

Something else that came up was things like platforms and elevators. These things move in a very predictable fashion, but they're not predicted. I think we can fix that to make them silky smooth.
