Merge branch 'fix-8456-lost-mouseenter' of https://github.com/dmethvin/jquery into dmethvin-fix-8456-lost-mouseenter

Merge branch 'fix-7340-focusin-focusout-bubble' of https://github.com/dmethvin/jquery into dmethvin-fix-7340-focusin-focusout-bubble

sadly the merge strategy doesn't work when doing an initial clone,
circumvent that

Adding core target to do jquery, minimization and lint

insterad of always update the submodules, now only "make all" will run
that, thus an "make jquery" will not update them

remove obsolete jq target

When  running make, the submodule update will remove all local changes.
Adding flag --rebase or --merge does solve the issue. rebase will
probably make it cleaner, but it might stop on conflict, thus --merge
will result in fewer (probably none).

Adding an helper funciton to pull the latest from all registered
submodules

Instead of the manual clone of sizzle and qunit, use git submodules
instead. this will ensure that all future releases can be recreated by
checking out an tag.

Fixes #8509. Makes URL regexp less overzealous and ensures it recognizes URL schemes which do not contain a conformant hierarchical structure ( as per section 2.1.2 of http://www.ietf.org/rfc/rfc2718.txt ). Also adds about: and adobe air's app: and app-storage: to the list of local protocols and provides a failover in case document.location is illformed. Unit test added.

Fixes #8456. Make sure parent is not null before crawling into its lap, so mouseenter is triggered on a mouseover event.

Fixes #7340. Use a single capturing handler to simulate bubbling focusin/focusout event on non-IE browsers. Allow native DOM methods to fire events other than the currently active one back into jQuery.

Moves Deferred-related code into a separate module. Context handling has been simplified in _Deferred.resolve and jQuery.when has been refactored for clarity (and minor optimization).

Revert "Fixes #8353. Adds a catch block in resolveWith so that the finally block gets executed in IE7 and IE6."

This reverts commit cacea6f7.

Make a new jQuery.support.noCloneChecked - splitting apart the previous feature detect relating to clone in IE, fixes the last remaining issue with IE 9 RC. Fixes #8365.

Fixes #8353. Adds a catch block in resolveWith so that the finally block gets executed in IE7 and IE6.

Makes the promise method of Deferreds a bit more readable by not using the variable declared as parameter trick anymore.
