special URL strings

http://ip/scripts/vidlink?userid=nate

will return url to broadcaster or the string "not broadcasting"

FUTURE:
make an API like did for zipcode so other a-html modules
can call
  InVideoChat(userid)
     returns "" or "ip:3080/files/image.htm"

specifically for use by powerbase when viewing a user record
so can have link to 'click here to video chat this user"
