  Bug fixes for voicemail user emailsubject / emailbody.

  This code change fixes a few issues with the voicemail user override of
  emailbody and emailsubject, including escaping the strings, potential memory
  leaks, and not overriding the voicemail defaults.  Revision 325877 fixed this
  for ASTERISK-16795, but did not fix it for ASTERISK-16781.  A subsequent
  check-in prevented 325877 from being applied to 10.  This check-in resolves
  both issues, and applies the changes to 1.8, 10, and trunk.
