The test case now mimicks the template environment more closely, so it's
possible to use render, load helper dependencies.

This also fixes assert_select, and similar assertions. Because view tests
and helpers generally don't render full templates assert_select looks
first in rendered and then in output_buffer to find the rendered output.

Additional `master'-only changes: Made the Action Pack Rakefile run the
ActionView::TestCase tests, and made ActionView::Rendering#_render_text
always return a string.

Merge abstract_controller/test_helper and new_base/test_helper since they are expected to run in the same testing sandbox

Get ActionPack's test running on bundled gems. This should make running tests on new machines, as well as CI, work well.

  * Tests can be run in isolation
  * Dependencies added
  * A few tests modified to avoid depending on AS deps 
    not depended on my files they were testing
