Make call queue numbers available as outbound caller ID numbers in User Settings templates

Currently numbers assigned to call queues are not available to be used as outbound caller ID numbers in User Settings templates. They appear in individual user settings, but when you are editing a template only site-level numbers appear. If you have numbers that point directly to a call queue, it will be likely that you will want that number to be the outbound caller ID number for members of that queue, and we don't want to have to set each user's caller ID separately without being able to use a template.
