Move messages

[stefanivic]

Discord apparently doesn't have this option by default. We could make a command to copy the users message into an embed and move it to the new channel.

The issue is that some users post multiple messages in a row, so we need to figure out how to pickup last X number of messages and move them.

Commands example:
!fed move @user 5 #self-promote;

Legend:
!fed - bot prefix;
move - the command;
@ user - the original author of the message;
5 - number of messages in the channel from the author we want to move;
#self-promote - destination of the move;
