[PD] Abstraction load time

That's because Pd tries to load the abstraction from everywhere in its 
-path (which can be a large number of places), then parses the text and 
uses it to create obects - all of this EVERY time it is instanced.

A quick and dirty attempt at caching abstractions in memory:

Also, I haven't checked the patches you attached, I hope you're turning 
dsp off before doing the dynamic patching and turning it on again (if 
desired) afterwards, otherwise the dsp graph is rebuilt after every 
object instead of just once (as far as I understand it).
