Add semi-colons
Bugfix. Check if from exists
Fetch own vcard on startup
Make sure fullname is saved to localStorage

Also make sure that logged in user's fullname is fetched from xmppstatus obj.
Don't show horizontal scrollbar
Add information icon
Make the info icon 16x16
Don't call disco#info for all chatrooms

It's way to inefficient when there are multiple chatrooms. Instead, I added an
info icon that can be clicked and which will fetch and display additional info
on the chatroom.
