Persist command aliases in alias.rb

[Faek]

It would be nice if the command aliases saved to and loaded from the database. I use a few aliases and it would be nice if they were there next time I started the bot.

It might be sufficient to do alias definitions either entirely at the configuration level (as in #70) or entirely within the database.

Open to discussion on that. Otherwise, we'll just implement both.

I have modified the script to store the aliases in the database and that's been working great for me. Personally, I wouldn't use the configuration-level aliases, I think that is more of an optional add-on feature to the database level aliases.

Would you mind making a pull request for that? I know that's a feature that's on our roadmap, and I'd love to poke through it if you'd be open to it, @Faek.
