Initial refactor of plugin system (darwin only)plugin-refactor

Darwin only for now since that's what I'm on, will migrate the others a
bit later. Trying out a different plugin system that probably makes more
sense as an interface to each other. Might shuffle things around even
more later.

This is based somewhat on Tsoding's audio visualiser plugin system, I
thought that was way more elegant (the 'state' object), as opposed to
whatever the hell we were doing.
