Subject: Improve row deselection and error handling in Table Source and
 Content views:  - Change the error dialog buttons to "Edit row" and "Discard
 changes" instead of "OK" and "Cancel"  - Correctly refocus the deselected row
  - Edit the first cell in the row after errors.  - Fix row deselection and
 error handling on the Table Source view
