TNL 3294 - Prevent double click creating multiple teams

LMS: increasing contrast of footer text

Increasing contrast in gray meta/date text on course dashboard

i18n fix

saleem-latif/SOL-565

Now using withDisabledElement to prevent multiple event handling. I've
attempted to write this as a common function in view_utils, so that this
approach can be used more generally, wherever needed. Includes a unit test.

Thanks to Christina and Andy for all their help on this one.

1. Add missing '_()' in capa_base.py & video_xfields.py
2. Fix a bug in instructor_dashboard.py that causes crash when ANALYTICS_DASHBOARD_NAME contains non-ascii characters.
3. Workaround for mis-extractions inside .underscore files when using gettext along with interpolate.

Improve response handling in AjaxHelpers

I've changed the logic so that AjaxHelpers keeps
track of which requests have not yet had mock
responses sent. This ensures that every response
is handled before moving on to the next one,
rather than always handling the last request.
My intention is that this won't allow bugs to creep
in where a request isn't fired and instead the test
responds to an old request. It also should ensure
that extra events aren't accidentally fired.

Improve team testing of routers

Remove "responsive" check before deciding whether to add a viewport tag.

A faster way to clean the .pyc files

merge release in to master for release 2015-09-22

Upgrade to the latest version of requests.

We also need to ensure that this tag is presented when loading xblocks
via the mobile app anyway. Since we're fine just giving responsive
content to everyone we don't need this check any more.
