modernizr.js is not modified because it's not our code.
En passant fixes:
* Delete two scripts that depended on a Yahoo service that
appears no longer to exist.
* The PhantomJS website no longer has a leading www.
* One script needed correction to *work* in strict mode.
* One script would only exit if a page loaded successfully.
(There may be other instances of this problem, this is the
one I noticed.)
When all tests were skipped, or when no tests were found, run-jasmine2.js
would raise an exception because ".alert > .bar.passed" doesn't exist. As
".alert > .bar.skipped" exists instead, and has similar interesting
content, let's use it!
Some banner elements (particularly the test run duration) have moved; this
change extracts the text values from the new locations. Also, the test run
duration is now populated after all tests are run, so include it as a "complete"
condition in the `waitsFor` function.
Closes#13459
