The current method which convert @mentions into Discord-compatible <@012345678901234567890> mentions first replaces roles in an arbitrary order, then each member in an arbitrary order.

This often leads to false matches. For example in a server with the user @bluebird and the role @Blue, the Minecraft chat message

Hey @bluebird what are your coords

turns into the Discord message

Hey @Bluebird what are your coords

It would be nice if the patterns were sorted by length descending so longer exact strings get matched first.
