Updating queries for the stream to be faster
Started converting the help section into a backbone view. Things missing are: some urls which were calculated and inserted into the yml, all the pre-existing erb templates are still there, it's still at /faq/faq, nothing has been tested, some of the questions don't collapse and expand.

changed the locales to have the hard coded urls in them because they can no longer be calculated server side. this is pretty crap because i'm going to have to change it for all the languages now so i might change my mind about this later.

deleted some unused views.
highlighting menu items when clicked. collapsing questions and answers on the static content help sections.

removed unused help haml templates.

put locales back to how they were and wrote a small js parser to swap in links to help views which have generated links in them.

using locales text for help section headers.
made a help view spec and cleaned up the views a bit.
moved call to help backbone view init to separate file included only on faq view.

extending loaded js locales.

cleaned up unused routes. removed some comments. loading help locales only on help view.

removed afterRender from backbone views. extended load_javascript_locales method to take a section.
refactored a bit in help section views. using backbone jquery selector shorthand and jquery each.
Actually load a different section when requested in get_javascript_strings_for, add spec for changes in JS i18n helper
Move help page initialization into backbone router
