I really like this idea. We've always reserved use of the revision 
number (Z in X.Y.Z), but our SWVersion code can recognize it.

As I see it, the advantages of dedicating the revision to .conf updates are:
1) We can add some new code to InstallMgr so that when a user updates 
his mods.d.tar.gz and it notices a new revision of the same minor 
version, it can do a silent .conf update.
2) A user who is still using Sword version <= 1.6.0 will get fallback 
behavior and still be able to update, they'll just have to download the 
whole module.

I'll start implementing this in a day or two, if no one raises an objection.
