[Tracker] Review request: needle-bookmarks branch

[Adrien Bustany <abustany gnome org>]

Hello trackeros,

I've pushed a "needle-bookmarks" branch to gnome git, which (suspense)
adds support for querying nfo:Bookmark from needle. It works well if
you use it together with the tracker-firefox addon
(git://git.mymadcat.com/tracker-firefox).
There's no history export yet, mainly since that would maybe belong
more to Zeitgeist than to Tracker...

Comments/reviews/criticisms welcome!

Cheers

Adrien
