MDL-42195 Bootstrap: Make bootstrap responsive images "opt-in".

This responsive image behaviour prevents setting of image sizes in text editors,
as well as a string of pix icon bugs / profile image bugs across Moodle.

We are switching to Bootstrap 3 syntax where you need img-responsive class to images
that want this behaviour.
MDL-44891 Behat: Add step to check attribute

This commit creates a Behat step of the form:

Then the "title" attribute of "Toggle visibility" "button"
should contain "Show"

This is useful because unless I missed something there is currently
no step that checks attribute values; this seems like a simple
generic step. Behat is intended to check user-visible effects in
the resulting HTML, and sometimes these effects are implemented
using attribute values (two common examples are the alt= attribute,
which is visible to screenreader users, and the title= attribute,
which is visible to all users; there's also the src attribute of
images, and lots of other possibilities too).

MDL-42462 - Feedback - Fix for WCAG 2.0 issue with Informational and Error Content Displayed in red

1) The same code used in other Moodle forms is now used in Feedback to display the "There are required fields in this form marked (*/Required field)" message at the top of the screen and each of the asterisks next to required fields.

2) Feedback specific styles (missingrequire, feeback_required_mark), which were used to highlight required and error fields, have been eliminated. These colours are now controlled by the common Moodle styles (mform1, mform, fdescription, required, req and error) that are used throughout the rest of Moodle for a more uniform appearance.

3) Field level error reporting now displays a message instead of just highlighting the field in a similar way that other Moodle forms do.
