[reSIProcate] Remote-Party-Id Header - Should it be a part of theStack

[Byron Campen]

	As long as you make sure to replicate the changes you make in each  
of HeaderTypes.hxx, Headers.hxx, HeaderHash.gperf, Headers.cxx,  
SipMessage.hxx, SipMessage.cxx, you should be fine. Running  
testParserCategories should highlight any problems. I'll look at your  
patch whenever I get a free moment, and test it out.

Best regards,
Byron Campen
