Edit work bibData

Hi,

We need to be able to edit the bibId of an existing work.  We used the bib Id validation code from the Identify Job screen.  We use the same code in both places.

This required a little refactoring of both the Identify step and the Work and Copies edit screens to make it fit properly.

See screenshot.
