Show @username mentions beside the PR instead of plain text

Would require some sort of mapping config so that the github names can be linked to slack usernames.

We have a dev channel, where everything gets posted, but some ignore it unless @username mentions happen. Having the @username would be great so they are alerted

That sounds like a good idea @ObjectiveTruth ! Would be good to make it config dependent as it might be too noisy for some teams. Thanks for suggesting it!

I'm thinking I'd be cool to have it default to the way it is now and then IF the mapping file is present, then use the mapping and do @username. This way its backwards compatible 👍
