Added CWE chart for 8-21 jan 2014
Fix some issues with saved scenarios

* Ensures that the correct title is set (and that other properties like
  "protected" are also set).

* Updated HTTParty from the two-year-old version we were previously
  using, for better compatibility with Ruby 2.1.

Closes #1743
Loading a scenario waits for the ETE response

Instead of setting the preset scenario ID, and then having the JS
client create a scenario on ETEngine, we instead use ActiveResource
to create a scenario on ETEngine before loading the "play" page.

This means that we only set the new `Current.setting` values once we
have a valid scenario on ETE, and prevents invalid sessions (a session
with no scenario ID) if they user quickly hits "back" after loading a
new scenario.
