[PD] Revising Help Files

[Jonathan Wilkes]

Ok, a few more questions concerning help patches:

1. What is a PD-meta GENRE?  Is there a list of them somewhere to 
choose from?

2. For PD-meta DATATYPE, take "gatom-help.pd" as an example: 
should this list acceptable DATATYPEs like "bang float list 
symbol", or just the datatypes that are most likely to be useful for  
this object, i.e., "bang float"?

3. Are all of the internal objects inherited from pd-vanilla really  
GPL?  I thought they were under the "Standard Improved BSD License"  
unless explicitly stating otherwise in the source code.
