app_voicemail.c: Ability to silence instructions if greeting is present.

There is an option to silence voicemail instructions but it does not
take into consideration if a recorded greeting exists or not. Add a
new 'S' option that does that.

+Subject: app_voicemail
+
+Add a new 'S' option to VoiceMail which prevents the instructions
+(vm-intro) from being played if a busy/unavailable/temporary greeting
+from the voicemail user is played. This is similar to the existing 's'
+option except that instructions will still be played if no user
+greeting is available.
