Add SayAlphaCase and similar functionality for AGI

Browse Source 
This adds a new dialplan application, SayAlphaCase, that performs much
the same function as SayAlpha except that it takes additional options
which allow the user to specify whether the case of each letter should
be announced for uppercase, lowercase, or all letters. Similar
functionality has been added to the SAY ALPHA AGI command via an
optional parameter.

* The SAY ALPHA command now accepts an additional parameter to control
whether it specifies the case of uppercase, lowercase, or all letters to
provide functionality similar to SayAlphaCase.
