Allow Discord links in Guild Descriptions to be clickable (as used to be the case)

This was a feature in the past to my knowledge, but no longer works. Some older guilds have discord links in their descriptions which are no longer clickable I was told that links in chat no longer being clickable is intended, though I see 3 arguments for allowing this. 1. Posting these links is already allowed in discord. (guild-recruitment channel). 2. Creating a guild requires a rank (I think Ace for SMP, Oni for RPG, not currently possible for Factions). That means that this is likely less subject to abuse than regular chat. There are a few caveats to this (it MAY be possible to transfer a guild to a player without a rank, also guild admins can change description according to /guild help, and they may not have a rank). 3. If you view a guild with a discord link in the description in discord (in bot-commands, /guild info) then it IS clickable there (and even if it wasn't, would be easy enough to copy/paste) Discord links are not immune to abuse, but in this case I think it tends to make sense to allow it. It also gives players an option to apply for guild membership if no members in that guild are online at the time.
