Easy Arel

With EasyArel instead of:

Thing.arel_table[:created_at]

you can say

Thing[:created_at]

EasyArel also creates class & instance methods named _ that reference your class, So in your model you can be all like

scope :recent, order(_[:created_at].desc)

You can't just use the brackets in this case, because that would just be an array. It's stupid, but I didn't feel like experimenting with any crazy operator overloading. I'm open to suggestions on making this better.

I doubt this is even a good idea, but whatever, tests pass.
