Share code between conflict resolution and the edit source switch

Each used their own implementation of building a form and submitting it.
The edit source one wasn't passing in the oldid, which caused edit
conflicts.

Also introduced a separation between form fields (for the action=edit UI)
and API options, building one from the other.
