Shoutbox

I made dt's scripts compatible with Opera and fixed some stuff that broke over time. (no idea if the web2messenger stuff still works, didn't test that)

The shoutboxcc script should work with Firefox, although I'm pretty sure I broke the betterrefresh script for Firefox..
The original betterrefresh seems to work fine in Firefox though.

shoutboxcc for Opera/Firefox
betterrefresh for Opera

In order to get shoutboxcc working in Opera, you'll need the Emulate GM functions script.
for /rand to work, get the Cross-domain XMLHttpRequest script. Then you'll need to have the Emulate GM functions script use the new XMLHttpRequest by changing the line "var request = new XMLHttpRequest();" to "var request = new opera.XMLHttpRequest();"
