ARI: Added new functionality to get all module information.

An http request can be sent to retrieve a list of all existing modules,
including the resource name, description, use count, status, and
support level.

The command "curl -v -u user:pass -X GET 'http://localhost:8088/ari/
asterisk/modules" (or something similar, depending on configuration)
can be run in the terminal to access this new functionality.

For more information, see:
https://wiki.asterisk.org/wiki.display/~bford/Asterisk+ARI+Resource

* Added new ARI functionality
* Information on modules can now be retrieved
