[development] D6 Cleaning up on module uninstall

[jeff at ayendesigns.com]

Good points from you and everyone else. On a tangent to this example, I 
think about the "completely uninstall" and "lose all data" messages, and 
that apparently the accepted way of doing it leaves many footprints. 
Sort of like when I have Windows remove an app and yet there are files 
and registry entries left all over the place, though in that case I 
don't think its by design. I don't know if this is also the case in D7, 
but if so, it might be fodder for a Cleanup module that accepts 
registration of all a module's pieces and then offers the user a choice 
between a 'standard' uninstall and a truly full one.
