Remove license from course outline page in Studio

This allows course authors to choose between two difference licenses for their
course content: All Rights Reserved, or Creative Commons. In the backend, XBlocks
that wish to allow custom licenses need only inherit from LicenseMixin, which
adds a `license` field as a string.

License information is displayed in the Studio editor view, and just below the
rendered XBlock in the LMS. In addition, if the course block itself has a custom
license set, this license will display just below the main body of the page
on courseware pages.

This entire feature is gated behind the LICENSING feature flag.

* Adds a credit course mode to indicate that a course
has a credit option.

* Hides the credit option from the track selection and
pay-and-verify pages.

* Shows different messaging for the verified track if
it's possible to upgrade from verified to credit at the end
of the course.

1. Fix sentence breaks inside `photo_reverification.html` and `midcourse_photo_reverification.html`.
2. Combine three setences inside `choose.html`.
3. Adding some punctuation marks to reduce duplicated strings with only different Punctuation marks in translation.
4. Move the colons inside the strings to be translated. This may be not necessary for now, but I think this may help translation by removing potential word meaning conflict.
5. Sorry for

Adds an /xdomain_proxy.html endpoint that serves
the proxy file from the xdomain library.  This
allows IE9 users to iframe in the proxy page
to simulate a cross-domain request with cookies.

The string "</script>" in JSON data would end the script element we're
embedding the data in.  To make sure the data doesn't disrupt the
script, we escape the slash as \/ .

This reverts commit 4a086f54.

When cdn is down specially in the country like china
and others user face problem as application doesn't
work as intended. Instead of making mathjax hard
dependecy I have converted it into soft dependey
so that it won't cause user problem to use application
smothly if mathjax is not present.

When mathjax is down discussion forum doesn't work
as we were using markdown.js with processor as
mathjax. Unavailability of mathjax raise error in
js which stops discussion to render. So I made
markdown independent of mathjax. Markdown now will
use mathjax when it is available otherwise ignore it.
