Heavy overhaul of buffer management and polyphony.
* Working polyphony when nodes are instantiated at desired polyphony
level (dynamic still doesn't work)
* Use shared silent buffer for disconnected audio inputs (save memory)
* Eliminate redundant patch compiling on delete and disconnect-all
events that have child events
* Fix a ton of crash bugs and other issues I've since forgotten
