* Bug fix
Current version causes 500 error since it is sending an array of from numbers to ClickSend. Changing the from number to 'hass' identifies all messages as coming from Home Assistant making them more recognisable and removes the bug.
* Amendment
Changed it to use 'hass' as the default instead of defaulting to the recipient which is the array. Would have worked if users set their own name but users who were using the default were experiencing the issue.
* Added DEFAULT_SENDER variable
* Add ClickSend notify service.
