This changeset allows for history and bookmark observers to be registered via
the category manager. This means the bookmarks service does not have to be
initialized at startup to register observers with it, as well as the history
service.

This adds a new function to nsNavBookmarks that determines if a place id is a
"real" bookmark (not a livemark child). It also makes a number of places use
this new function to unify and simplify a number of code paths.
Additionally, it changes how frecency is calculated for bookmarked items. If a
visit is bookmarked (aIsBookmarked is true in CalculateFrecencyInternal), the
visited bookmark bonus is now added for all visits. The visit bonus was also
cut in half for bookmarks so TRANSITION_BOOKMARK will still end up with the same
value (150).
