Custom message on wp-login.php when redirected there from WW

[boonebgorges]

When an 'Ask for Help' request comes from WW, we redirect it to wp-login.php if the user is unauthenticated.

This redirect should include a special param (say, ?is-webwork-redirect or whatever), and when that param is detected, we ought to show a special login message. I think the generic message should be something like: You have been directed to %s from WeBWorK. Before posting a question, you must log in using your %s credentials, where %s is the name of the site (in the case of the OL it would be WeBWorK on the OpenLab).

I'll put a filter on this so that it can be modified. I assume we want something a bit more tailored for the OL, like You must log into the OpenLab to post a WeBWorK question. Other suggestions on wording are welcome.

I've made the change. Here's what it looks like out of the box:

I customized the text for the OpenLab as follows:

Happy to change the wording in either case.

This looks good, thanks!
