[Command] Remind

[ctsstc]

I would like something similar to slack's remind command.

ie: remind [@user, #channel, me] [something] [at,on,next] [time]

This could be ephemeral, but if the bot was restarted, updated, or crashes it would lose the current cron jobs, so it would be best to commit these to a database and load up any pending jobs at start.

I remember running across an article about making something like this, or at least parsing out dates, maybe they went overkill with machine learning?.. We can start with something basic and rigid though like a simple regex. Maybe something like:

/^(@|#).* (.*) at (.*)/
