Summary: Made mpkg-find-mod that looks in all packages for a specified module
         file. Now mbs-mod is completely global. Not sure if this will always
         be a good thing, but it will make the initial cleanup much easier.

         Functions working nicely are:
            mbs-func (looks for function everywhere)
            mbs-mod  (looks for module everywhere)
            mbs-git  (uses mbs core git repository)

Testing: loadmbs and played around with the above functions
