Subject: [PATCH] Save the useMathView user setting on the User Settings page

The User Settings page shows a 'Use Equation Editor?' option when
$pg{specialPGEnvironmentVars}{entryAssist} is set to 'MathView', but
the useMathView parameter it submits was never read when saving, so the
selected value was silently discarded and the setting reverted to the
course default on every reload.

Include useMathView in the change detection and save it together with
the other display settings, matching how displayMode, showOldAnswers,
and useMathQuill are handled.
