app_originate: Add ability to set codecs
A list of codecs to use for dialplan-originated calls can now be specified in Originate, similar to the ability in call files and the manager action. Additionally, we now default to just using the slin codec for originated calls, rather than all the slin* codecs up through slin192, which has been known to cause issues and inconsistencies from AMI and call file behavior.

Subject: app_originate

Codecs can now be specified for dialplan-originated
|

calls, as with call files and the manager action.
|

By default, only the slin codec is now used, instead

of all the slin* codecs.
