Edits older than 60s are not delivered

[devkev]

If someone edits a message that was originally sent more than 60 seconds ago, the notification of this event is not delivered to IRC users. However, web users will see the edited message. IRC users may justifiably also be interested in the revised content, even though it's over a minute old.

What's the rationale behind this arbitrary limitation?

It would be useful if it could be customised somehow.

A workaround is to edit lib/event/message_edit_event.rb and make MESSAGE_EDIT_THRESHOLD_IN_SECONDS be very large, and then run a local oulu.
