        <rdar://5554130> DatabaseTracker.o has a global initializer

        Since DatabaseTracker is a singleton, it makes much more sense to keep the database path as a member variable.
        Now constructing the shared DatabaseTracker no longer implicitly opens it - It is only opened when the databases 
        path is set.
