Update 4.7 to D6

Here's what I did:

1) Take a D4.7 site, upgrade Core to D5

2) Update Core of that site to D6

3) ran update for image module (D4.7->D6): BOOM!

The files tables have changed and the upgrade failed.

I think the D5 updates should be removed and a warning be put out /or/ the updates should be reworked to work for D4.7 to D6.
