[PD] Updated pd-extended

[puredata at 11h11.com]

Hi,

Would do anything to finally include mtl abstractions to pd-extended.  
I can build on Windows, Mac, Linux & the RPI.

Will try to poke Hans about the code diffs on #dataflow. Should we  
(anyone interested in updating pd-extended) have a chat (irc, hangout,  
whatever). I am sure Hans will be willing to gives 30 minutes to help  
us help him.

Let's bang it.
