Applying patch from #5288 (notification: prevent out-of-office replies)

Apply Noah's patch from #5203. Thanks for the patch.

Also remove the Sender SMTP field to improve compliance with RFC2822 that specifies (section 3.6.2):
* ''If the originator of the message can be indicated by a single mailbox and the author and transmitter are identical, the "Sender:" field SHOULD NOT be used.''

Should fix up #2766: usernames with '@' are always treated as email addresses

A new `ignore_domains` option has been added to the notification settings:[[br]]
a comma-separated list of domains that should not be considered as being part of email addresses.

Triage: Sub-branching for non-fallback version of this.
I think the benefits of non-JS fallback will be outweighed
by the complex, redundant code and difficulty of maintenance.

Triage: Display/hide the actions menu for the non-JS system.

WorkFlow: clarify the get_ticket_actions doc string.

WorkFlow: Tweak the set_owner and set_resolution controls.
