* Refactor peer_grading_problem to lookup track_changes variable by problem location.
* Whitelist ICE insert, delete tags
* Adds ICE multi-user-editor insert and delete tags to the peer grading sanitize_html whitelist.
- add reset button
* Introduction ICE means we need its inline tags to get passed through
to the feedback target, but we don't want malicious peer feedback
providers introducing <script>, etc, so we use lxml.html.clean to
scrub peer grading input.
* Adds feedback URL autoheating.
* Allows ICE <insert> and <delete> tags but not others.

updates.
The home icon and discussion topic drop-down icon now have text that is
visible only to screen readers. The visual change between the icon and the
topic name with down-arrow is now achieved with the CSS visible property
instead of the opacity property, so only one at a time will be visible to
screen readers as well as visually.
Modal dialogs should manage keyboard focus, ensuring that users can't
tab out of the modal dialog and back into the page itself (effectively
moving “behind” the dimmed modal). On the last focusable element of the
dialog, return focus back to the first focusable element.
Also move the close button to the start of the dialog's section, making
it the first focusable URL, to ensure focus matches the visual
representation of the dialog.
