polyTopoChange: Removed restrictive faceZone functionality

Now faceZones are handled directly by the applications and the new
faceZone::topoChange function so that any face can now be in any number of
zones, significantly increasing the flexibility and usefulness of faceZones.

This completes the generalisation of cellZone, faceZone and pointZone to support
multiple zones for each cell, face or point respectively.  Next step will be to
make zones polymorphic and run-time selectable so that they can alter during the
run and adapt to moving meshes for example.
