Finished deletion. Assorted bug fixes.

- columns can now be deleted/undeleted
- reset active row if deleting that row
- grammar now accepts an empty file
- when a non-canvas entry becomes editable, we set the focus to it
- when adding the first reference to a frame, make it active
- when deleting the active reference to a frame, set the pointer to NULL
- measurements didn't have a drag_new action, causing trying to create them to
  crash fped
- offset field of measurements was incorrectly labeled "width"
- fixed operator precedence in gridify. Someone needs more sleep :-(
