Andrew Nicols 87d71ecf69 MDL-49324 grade: Ensure weights adjusted message is displayed
The grade settings page displays a message to inform users that weights
have been adjusted if they did not previously add up to the required 100%.

With the change to sometimes displaying a progress bar, whether the message
is displayed must be calculated immediately after the regrade took place,
and before the page redirects.

I have added a callback with arguments to the regrade_if_required function
which is called immediately after regrade has taken place (regardless of
whether the progress bar is required).

This callback modifies the PAGE URL such that the redirect message will be
displayed after the redirect. This does not use the session as the message
should only be displayed immediately after a change. If the user does not
click on the continue button after the progress bar has been displayed, and
comes back to the page later, this may be confusing.
