Allow select with Arel and count as well as calculations with Arel
It allows a query like `User.select(:name).count` to be written
using Arel as `User.select(User.arel_table[:name]).count`.
It exposes the calculations API to accept Arel nodes:
`User.count(User.arel_table[:name])`, `User.sum(User.arel_table[:id])`,
`Account.average(Account.arel_table[:credit_limit])`,
`Account.maximum(Account.arel_table[:credit_limit])` and
`Account.minimum(Account.arel_table[:credit_limit])`.
