#130 - Fix dashboard refresh.

* Was broken because /pipelines.json was not resolving.
#130 - Fix 'trigger with options' material search.

* Was failing because of CSRF protection. This shouldn't even be using
  POST. Should use GET. But, that involves too much change right now.
  Since the dashboard might be rewritten soon, leaving it as POST and
  disabling CSRF protection for only that method (which is not making
  any POST-like changes anyway).

#130 - Fix dashboard refresh.
Revert "#130 - Fix 'trigger with options' material search."

This reverts commit 42445f5a77110fdb1d25808923f0877f37afed73.

Will fix by converting the POST to a GET, instead. It's possible.
#130 - Change POST to GET for material_search.

* This is the call used by the material search box in trigger with options.
  It used to do a POST. Now, it has been changed to do a GET.

* Still allowing a POST to it as well, like earlier. Might need to check
  and remove later.
#130 - Do not use layout with material_search call.

* Was trying to use a layout (pipelines layout) and failing.
#130 - Remove ability to POST to /pipelines/material_search.
#130 - Fix environment edit buttons.

* Also, new spec written for show.html.erb of environments.
#130 - Fix environment variable add.

* Was broken due to ERB change between Rails versions. Needed to use <%= instead of <%-.
