also add new command findings:
* undocumented command GSB
* syntax and other errors fixed
* explode a bit of xml in places that were a bit too long
* find out what a "merchant cab" file is (one line of xml)
information for MSNP4 found: adds the client codebase parameter to SND and CVR (and an empty to CVQ, but that lasted all the way to MSNP7 lol, does that for MSNP3 fallback too which is kind of funny)
18 commands left.
