Support: Make the support matrix for iOS 6 match iOS 7 as well
Event: Call underlying stopImmediatePropagation when present

Fixes #13997
Core: Bump timeouts to stabilize doc ready test

The "document ready when jQuery loaded asynchronously" test fails all the time
in iOS7 and sometimes in other browsers. Bumping the timeouts *might* help
these other browsers to be less flakey here.

Fixes #14882
Build: Change the timeout for the weekly job from 4h to 1h
Core: Change the sleep time in dont_return.php to a sane value

PHP sleep function accepts time in seconds, not milliseconds; the previous
value was starving the PHP FPM process pool.
Event: Don't test stopImmediatePropagation in Android 2.3

Android 2.3 doesn't support stopImmediatePropagation; jQuery fallbacks
to stopPropagation in such a case.
Event: Simplify the logic behind blacklisting Android 2.3 on one test
Core: Change the sleep time in dont_return.php from 100s to 30s

Half a minute is more than enough for the test to finish even in the slowest
browsers and in case of starving the PHP FPM process pool, one has to wait
for only half a minute to try again.
