Added MSP, MXP, MSDP and a few other protocols

that may be used by MUD type games so their login screens can be captured without the odd chars.

If you connect to, say, coffeemud.net then you'll see various telnet negotiation characters for various mud protocols that are understood by MUD clients. These will help termcapture_lib.js filter those out so they're not on the login page. I figured it'd be just as easy to put them here rather than create a separate lib for muds.
