Since there is now a globally available function for saying someone's name, a LOT of

functions in app_directory can be removed since the ODBC-specific lookups are accomplished
within app_voicemail. This change greatly reduces the amount of lines in app_directory that
were solely for the purpose of looking up a name when ODBC_STORAGE is specified for voicemail.

This commit also makes the name-saying interruptable via DTMF.
