ARI: Added new functionality to reload a single module.

An http request can be sent to reload an Asterisk module. If the
module can not be reloaded or is not already loaded, an error
response will be returned.

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

For more information, see:

* Added new ARI functionality
* Asterisk modules can be reloaded through http requests
