[PD] Pd-extended 0.43 updates: lots of new editing features

[ico at vt.edu]

Nice to hear about some progress in these important areas. BTW, did  
you merge vanilla MagicGlass and nlet highlighting or the one from the  
pd-l2ork? I ask this because vanilla implementations of both of those  
have a number of issues, including unnecessary cpu overhead and  
potential instabilities.

Best wishes,

Ico
