Add locking to entries when they are being edited

[zackkatz]

Gravity Forms supports this with GFEntryLocking; add this to Edit Entry when an entry is being edited as well.

Entry Locking is not working for the View (nothing happens when two different users try to edit the same entry at the same time).

That's only an issue on the front end, the feature still works properly on the Gravity Forms interface.

Tested from GV v2.10.2.2 down to v2.9.4 and the issue persists for all releases.

User feedback:

A. Display frontend messages to users when > 1 user tries to edit an entry.

B. Allow a "take control" process or a message to be sent to user who first opened the entry to edit it. If the first user does not reply or take action within a user specified period of time, control could be diverted automatically to the second user trying to edit the entry.

@rafaehlers Please test this functionality—it used to work, but we're having reports that it's not working anymore.

I'm trying to test the Entry Locking feature with no success.
I have the setting enabled in the view. While logged-in as 2 different users, and one entry is being edited with the first user, when I open that same entry to edit with the second user it doesn't give me the notification that the entry is locked, I'm allowed to edit the same entry with 2 different users at the same time.
Maybe I'm missing something?

@omarkasem can you please check this one too?
