Undo: Implement undo of dive site name editing

Browse source 
Implement an undo command that edits the name of a dive site.
Connect it to the dive site table, so that names can be edited
directly in the table.

Send signals on undo / redo so that the dive site table and
the dive site edit widget can be updated.
