41	"Add support for ""lockable"" record edits"	Kris Deugau		"Locking (advisory or otherwise) will help prevent multiple concurrent changes from getting done badly and ending up publishing wrong data.

Concept:  On clicking to edit, a token is pushed to an advisory table and flag is set in the session.

If the record is updated, the token is tagged for clearing in <n> seconds (60?  can't be too short) after the event (to prevent unlock-update races) - other sessions can see the update time and show a warning with the ""new original"" record vs their new update.

If some other action is taken, the session flag and advisory token are cleared so other clients don't block."	enhancement	new	trivial
