form_tag, link, CSRF changes

Plug 0.10.0 moves CSRF tokens from cookies back to sessions. To avoid future bumps on the road, a get_csrf_token/0 function has been added to controllers and imported into views. Update all your csrf token reference code to use the new function. Additionally, form_tag and link helpers have been added that will inject the csrf token for you automatically. You should transition to these new functions where possible, ie:

  <%= form_tag("/hello", method: :post) %>
    ... your form stuff. csrf is inject for you
  </form>

Comparative Benchmark Numbers @ Rackspace

I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.
