Bug 25334: Add generic 'phone' message transport type

As bug 25333 changed the 'phone' transport type to 'talkingtech', we can
now re-add 'phone' as a transport type again, and allow it to behave and
support the same notices as the email transport type.

Test Plan;
1) Apply this patch
2) Run updatedatabase
3) Restart all the things!
4) Disable TalkingTechItivaPhoneNotificationi if enabled
5) Enable new PhoneNotification system preference
6) Go to a patron's messaging preferences, not you can select the
   'phone' option for all the same notices as the 'email' option
7) Enable the phone option for all the message types
8) Browser to the Notices and slips editor
9) Add a phone notice version for each notice you wish to test
10) Test some notices ( CHECKIN, CHECKOUT, etc )
11) Notices should show in the patron's messages as 'phone' notices
