* Brought search results against WGs and document titles into consistency with results from searching for individual documents
* Added the IPR count to the link on the documents main page (when not zero)
* Built on Henrik's reimplementation of all_related_*, making the *_related_* functions return DocAlias lists consistently, and added corresponding _relations_ functions to get lists of actual RelatedDocument objects.
* Added getting the DocAlias with the same name to Document
* Added getting related IPR disclosures (as described in the first bullet) to Document
* Simplified ipr/related.py
* Removed the use of DraftLikeDocAlias and IETFWG from ipr/search.py. Retooled the various search functions and templates to use DocAlias and IprDocAlias directly.
* Removed dead code from ipr/search.py
* Removed the special handling of WG 2000 from ipr/search.py
