[#12625] Stops prodromus from eating http/https links

The webchat UI previously ate http/https from links as a form of
simplifying/beautifying urls but that proved bad when users copy/pasted
logs so now it displays full links instead of simpler ones.
Adds a stats monthly backup custom command.
Prevents a user from locking an issue indefinitely.

Previously, Stats gave users the right to lock issues indefinitely with
no expiration. This commit fixes that by settings a timer on each lock,
if the user takes more time than the one set in settings.CONFIG, his
page will refresh and unlock the issue for others to edit.
