Followup commit for #7340 test case; make sure second test fires properly on IE by focusing to another element rather than blurring off the first.

- Removed special page, just needed another test in the fixed offset tests

- Checks it's position related to scrolling

Fixes #8203. Remove some misguided nulling of elements done in the name of IE memory cleanup. Based on a patch by davidmurdoch in pull 226.

Fixes #8692. Strange FF4 bug: values changed onto the arguments object sometimes end up as undefined values outside the $.when method. Cloning the object into a fresh array solves the issue.

Further fix for #3333, refactored marginRight css hook to use jQuery.swap and computed. Thanks timmywil

Added css hook to work around bug in WebKit computed margin-right. Fixes #3333 - .css("marginRight") is incorrect in WebKit

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).

unless jquery.js has been updated, no minification should occur

closes: #8519

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.
