It takes the destination you'd like to send to, which filters to apply
(defaults on mass mentions, and invite links) and any other parameters
normally accepted by destination.send
This should realistically only be used for responding using user provided
input. (unfortunately, including usernames)
Manually crafted messages which don't take any user input have no need of this
Returns
-------
discord.Message
The message that was sent.
