Add 0.12.7 from the gnome overlay. Used by gnome-3.2. Lots of changes and improvements, including optional firefox and thunderbird support (firefox support is controlled by USE=firefox-bookmarks so that users don't enable it by accident, since it can slow down the browser). Some ugly hacks are required to avoid thunderbird- and firefox-related access violations. The nautilus extension has been split off into a separate package (nautilus-tracker-tags) to avoid circular dependencies with nautilus-3.2.
