Wallerscript 3.05

This is just a couple of bug fixes after some complaints from some users (i.e., if $cmdchar was set, then when the script reported a wrong syntax, it didn't take it into account, and there is a new $cmdcharmsg variable).

Among other things, we've switched to using the proper Tcl method for control codes, and had a proper implementation of ws_isauthed (i.e., the bot now msg's you if you're not authed on all commands, rather than some).

We've brought back /msg notice and /msg privmsg, so you can select how the bot replies to you. This means the userfiles have changed, so read the Changelog (in README) for the very simple command of how to change it.
