Header updated for accessibility

Release candidate 1.1.12

Actually check if staff grade is staff grade

Boy scout rule

Previously, there was no way for ORA to check whether a given score
was a staff score or not; we've leveraged the annotations stored with
those scores to expose and use that data.

This reverts commit 7cd8e282, which was accidentally pushed to master

1.1.11 version bump

Unpin pytz version

Enable the preview button if the submit button is enabled.

Really, the preview button should be enabled whenever there
is something to render. Since the submit button will only be
disabled upon initial rendering if there is nothing to submit,
it seems like a reasonable proxy.

Make disabled buttons truly disabled.

Previously this was happening in LMS through edx-platform CSS, but it was not happening in Studio.

Does not include Studio editing buttons.
