Added RecognTags.

- items are described in serialiser.
	- util functions in util/rsrecogn.cc are used to manipulate it.
	- these are attached to GxsIds, with new interface fns.
	- Associated Signing Code is in a separate program.

Other Tweaks.
	- Added RsMemCache::erase()
	- Added RsTlvStringSetRef 
	- Fix for rsturtleitem (already added to trunk).
	- Formatting and debugging.

Status: There is a bug in RsGenExchange::updateGroup which prevents full testing, 
The basic generation, parsing and validation functions have been tested and are ok.
The processing as part of p3IdService still needs to be fully debugged.
