Add support for sending message reactions

[Hoodgail]

I appreciate that you can view message reactions. But will support for reaction from airmessage web and mobile be possible? There could be a context menu with the reactions components when you right-click.

This issue revolves around the face that Apple's iMessage API is very limited, and unfortunately doesn't support many of the newer iMessage features. A workaround is possible via privilege escalation, though this has security implications.

As this functionality would have to first be supported by AirMessage Server, I am moving this issue there.

Here is some documentation from the BlueBubbles team on how they parse/send tapbacks
