[KFSQA-838] Added in a small API refinement that should allow us to fill in required fields on demand. Also moved some non-Account-specific errors out of the Account step definitions file and into the generic errors step definition file.
[KFSQA-838] Added #absorb to the API as a way to sop up document data from a page when doing a document copy (like when you copy an Account). You need to provide a hash from the associated page(s) that defines what consititutes the information you are looking for, but I think it is still kosher because during this sort of action, the data on the page really does represent two objects.
