Content that doesn't fit on the screen was causing the viewport to be
the wrong size on mobile devices resulting. This forces wrapping for
long content instead of letting it force the viewport size.

Otto is gaining the ability to temporarily disable payment
processors. If all are disabled, no checkout buttons will appear on
the payment page, and so we need to communicate to the user that they
cann't pay right now but should try again later.

Added error message incase user specified start or due date without time and also added start date and due date comparison validation in ccx coach dashboard validation.

1. No string concatenation should be used in the gettext function.
2. Some extra parentheses should be used in coffee script, to avoid the following situation: in coffee script, the call ```gettext "text to be extracted" + "text should not be extracted"``` will be translated into ```gettext("text to be extracted" + "text should not be extracted")``` rather than ```gettext("text to be extracted") + "text should not be extracted"```.

Adds UTC time to the "Today's Date" block, and a fuzzy/relative
timestamp to all other displayed dates.

This was originally contributed upstream by Stanford, circa 2013.

We neither use nor support this feature in its current implementation,
and in fact, we may never have used this production. Until recently, we
had additional chat/Jabber code [1] (in the form of a Jabber djangoapp in
LMS); context there suggests this feature may have never been more than
a prototype. The original author is no longer on the team, so I can't directly
confirm this on our end.

Do you use this feature?

Stanford had already abandoned this Jabber-backed chat implementation,
in favor of an IRC backend, by the time I joined the team in early 2014.

Having the messeges embedded into onclick attributes was fragile because
it could break if the translated string contained special characters
such as single quotes.

Rather than trying to escape the special characters inside the onclick handler,
move the translatable strings into separate h-escaped data attributes and interpolate
the values in the (already existing) jQuery click handler rather than in the
inline onclick handler.

This makes the javascript code more consistent as well as fixes the problem
where the popup would break if translation included single quotes.

Enabled behind the
`SelfPacedConfiguration.enable_course_home_improvements` flag.
