After changing this effect from SEND_MESSAGE to just MESSAGE by accident, then pushing a fix for it that somehow didn't end up in any release and ultimately deciding to leave it at MESSAGE, we somehow ended up in a state where the default config generates a SEND_MESSAGE effect whilst the effect engine only knows MESSAGE....

This update therefore adjusts the default configuration and the effect explanation to say MESSAGE instead of SEND_MESSAGE to finally end the confusion

IF YOU CURRENTLY USE THE MESSAGE/SEND_MESSAGE EFFECT, MAKE SURE IT SAYS "MESSAGE"
