commit 5713c49c8480639f08f7fff82fb5a40e8566e1dc
from: Alexander Barton <alex@barton.de>
date: Tue Mar 18 13:55:38 2014 UTC

Implement user mode "F": "relaxed flood protection"

ngIRCd relaxes its flood protection for users having the user mode "F" set
and allows them to rapidly send data to the daemon. This mode is only
settable by IRC Operators and can cause problems in the network -- so be
careful and only set it on "trusted" clients!

User mode "F" is used by Bahamut for this purpose, for example, see
<http://docs.dal.net/docs/modes.html#4.9>.
