tfCmdParse

I do not use the spedwalk.tf or map.tf (conflicts with other code I use). spedwalk.tf also does not handle all the directions available on 3K. So I wrote this to facilitate movement and other tasks.

;;;CmdParse = Command Parser with Repeat ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; DO NOT USE FOR COMMANDS WITH %* You can use $[] however
;
; usuage:
;
;/CmdParse [-s"<CmdSeperator>"][-n"<NumSeperator>] \ 
;[n<NumSeperator>]<cmd><CmdSeperator>[n<NumSeperator>]<cmd><CmdSeperator>....
;    <CmdSeperator> defaults to "/"
;    <NumSeperator> defaults to "-"
;    and <cmd> is any string
;
; Examples:
;    /CmdParse 21-n/3-ne/s/enter
;        will do n 21 times then ne 3 times then s then enter
;
;    /CmdParse #give corpse/absorb
;        will do #give corpse then absorb
;
;    /CmdParse -s"~" qtrance #give corpse/absorb~woo
;        will do qtrance #give corpse/absorb then the woo soul
;
