someone likes to chat? well, I do. here's a new IRC client. it connects directly into our irc.datacore.ch / #orxonox channel with a random nickname. use the "say text" command to write text into the channel. there are some more commands without a shortcut, type "IRC" and tab.
please update your media directory.

for some reason, irc-client and telnet-remote don't work together. please use only one feature at the same time. I'm not sure if it's a bug in TCL or in my TclThreadManager class. The problem also occurs with irc or telnet in parallel with another busy tcl-thread… strange thing.
