First Implimentation is complete. Have not had time to fully test everything, but anyone that wants to try it out, feel free.
Just place the Icons folder inside the base MUSHclient folder, and install the FF3/6 Font. Then add the plugin from the File menu in MUSHClient, and log in!
If you were logged in while you added the plugin, you will need to type 'setupgui' and 'setname yourname'.
