Radical differences in Bookmark storage

Browse Source 
Had some problems with PuSH and Salmon use of Bookmarks; they were
being required to generate Atom versions of the bookmark _before_ the bookmark was saved.

So, I reversed the order of how things are saved, and associate notices and bookmarks
by URI rather than notice_id.
