Feature Request: Mention users

[jsmit99]

It would be great if we could do something like mentioning users (with autofill) when typing @adammparker (like the github comments work).

Hey @jsmit99, I agree it would be nice if we had that but it would either need to be custom-built or we'd need to pull in some auto-complete textarea Vue component which means we would then have a 3rd party dependency within the package - the current version of this package is so simplistic which is very nice (easy to maintain).

I'd probably want to generalize this behavior so it would allow the developer to make autosuggestions for any number of items (not just users potentially, i.e. any notifiable model) - it gets complicated pretty quickly.

Maybe the most ideal version would instead allow the developer to completely substitute their own custom textarea implementation into the Comment panel somehow, but that's also not something we are looking to support for now.
