Minor regex issue

[fl0g]

The regex for direct mention will fail if another user is mention in the message.
I.e. regex <@([WU].+)>.+ will match "<@uuser1> message <@Uuser2> more message" to the last ">" in the string.
Suggest to change to <@([WU].+?)>.+

Encountered this when I wanted the bot parse commands to interact with other users.
