This reverts commit 04cc446d.

I reverted it because apparently we want to use: select([:a, :b])
instead of select(:a, :b), but there was no tests for that form.

allow select to have multiple arguments ie. Post.select(:id,:name,:author)

Simplify the test by using id and name.

refactored 'assert_redirected_to': local call to validate_request! will be called in assert_response already. changed names of local variables in order to recognize the semantics a bit easier.

Simplify the test by using id and name. `id` will be the only real sort criteria in any case as it's unique.

Allow a route to have :format => true
