modules_k/xcap_server: Added new pseudo variable $xcapuri(name=>xuiddomain)

- $xcapuri(name=>xuiddomain) contains the domain part from $xcapuri(name=>xuid)
  The xuiddomain can be used with www_authorize() and www_challenge() if you
  want the realm to be based on the user's domain instead of something
  hard-coded (like "xcap").

  This is particularly useful if you need multi-domain support, don't want
  plain-text passwords in the subscriber table, and also don't want to have to
  create two entries for each subscriber (one with the SIP domain as the realm
  and one with "xcap" as the realm).
