Put plugins into external AppDomains

[DerPopo]

Creating an AppDomain crashes the game (either it's my or unity's fault).
In the meantime the current AppDomain is used to load plugins and therefore plugins can't be unloaded/reloaded.

Was browsing the Unity forums when I found this.

This thread implies custom appdomains are possible.
