Bug fixes for voicemail user emailsubject / emailbody.

Browse Source 
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.
