This idea is taken from the game OGame, where their kind of legion can have an
url (seperate setting) where its linked when you check your own legion page or looking on legion info page as non-member.

this would be good to seperate announcements to pure info/text, and have an seperate row and setting for perhaps a private forum outside the game ect.

suggested commands (to fit the current legion cmds):
/lu <url>
/legionurl <url>
