Merge from virt lib
Add the _form of the date search terms to the manual, e.g., _today.
Virtual library changes:
1) when editing, use a combo box so the user can change which VL is being edited.
2) add option to build VL from saved searches
3) add separator between "*current search" and the list of VLs to make it harder to click in the wrong place.
