Subject: Add avatar and attachments to llRegionSay

  llRegionSay will now message avatars on chan 0
  and will message attachments on the avatar that
  listen on channels other than 0.

  This behavior is consistant with the LL
  implementation as tested on regions in Agni
  with one exception: this implementation does
  not include issue:
