Upgrading EntityForm from 7.x-1.x to 7.x-2.x

For 7.x-2.x the Rules integration logic has been moved to a separate module, Entity Rules.

This allows 7.x-2.x not to have a Rules dependency. It also allows Rules integration to be used for all other fieldable Entity Types. The problem this creates is Rules that worked with 7.x-1.x will not work with 7.x-2.x and Entity Rules.

The upgrade process is manual but relatively straightforward and is outlined in this issue: #2134619: Upgrade process for upgrading Rules from 1.x to 2.x
