Send Overloads!

Options are great!

This update adds channel name and security options in all the send overloads. Security Options can be set to None and channel can be set empty or null. Both options are optional and default to None & Default Message Channel.

This means you can now once again select the channel (Yes, it was missing from the lib. for a version or two.. or three 😒), but you can now also authenticate and encrypt messages! Adding even more security to the library.
