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-38183 themes: Removed redundant css rules for #adminsettings .form-overridden from standard and formal_white.
MDL-41511 blocks: improved how custom block regions were being rendered.

There is a new theme property 'blockrendermethod' that can be set by the
theme in its config.php and tells Moodle what method it is using to render
blocks in the layout files.
Either blocks, or blocks_for_region.
Then when adding custom block regions to a page content we ensure we use
the same method the theme is using elsewhere.

This is really a hack becuase we (I) didn't properly deprecate
blocks_for_region when I added the blocks method.
