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
