Request: `php artisan` alias

[LimeBlast]

I would submit a pull request for this one, if I knew how to do it - but I don't.. sorry.

Anyway, I think it would be worth adding a .bashrc alias which maps php artisan to art. This would save our keyboards and keyboards a little bit of wear and tear :)

Haha sounds good, I'll look into that, I'm hoping to set aside some time in the next few days to clean up a few of these issues :-)
