[TermInfos, FieldTypes, Tax ValueTypes]
- Fixed some FieldTypes namespaces
- Added TaxonomyFullValueCollection. Still missing entity binder converters from that and TaxonomyFullValue.
- Reworked TermInfo, TermSetInfo, TermGroupInfo, TermSetInfo and added the TermInfoFactory to control their creation from SharePoint objects.
- Still not sure if the "empty termGroupInfo means default site-collection-specific term group" convention is a good idea. Introduced the IsDefault flag in the TermGroupInfo instead (so we aren't prevented abitrarily from reaching all the way up to TermStoreInfo).
