removing red indicator

red indicator was actually green... so it is now removed!
now icons added

added online indicators; links to fansites tibiaml, pskonejott, exhiti,
guildstats (this one not completed); Moved some methods that can be used
in common to a general JS file (like htmlDecode), so there is no need to
duplicate methods or pass them through unsecure messages; and changed
the way the message listener works.
