ResBuf

Some of the function names have been changed.  ResourceBuff has a pending deprecation warning.  ResBuf has an experimental warning.  
Yeah.  I don't think I even like the concept of a "pending deprecation" warning.  "Deprecation" sort of means "pending removal" in a way.  So I would be fine to even leave no warnings on resource buff until it is actually deprecated.  Regardless - I'll happily remove this warning.
