It's already set in jQuery.Event, and copying it can clobber values set by the caller, e.g., the UI widget factory.

Landing pull request 520. Unset the complete function just before calling it to avoid an exception creating a loop. Fixes #5684.

Fixes IE7 test suite. Keep the testElement attached and set necessary styles on it to fix the offset with margin test.

Fixes a fail in unit/traversing. Use an iframe's document for creating the html5 fragment when necessary.

* 'fix-8789-rwldrn-fix' of git://github.com/dmethvin/jquery:
  Minor cleanups to code. Futile effort to get IE to pass the unit test.
  propHooks now an object with `props` array and `filter` function.
  Moves mouse properties to mouseProps
  current state
  Removes early return loop, must copy properties
  Shortcircuit fix if possible
  More ref localization
  Remove unnec. empty line
  More reference caching
  Cache reference to propHook lookup and result
  Restore this.propHooks => jQuery.event.propHooks for better gzip compression. Thanks gnarf
  Adds notes re: crash status of fix conditions
  Moves key event fixes to own even prop hook defs
  jQuery.event.propHooks => this.propHooks where possible
  Removes pageX pageY from prop list
  Updates rmouseEvent
  Implements jQuery.event.propHooks. Fixes #8789
  Adds implementation tests for jQuery.event.propHooks #8789

Revert QUnit. Recent start/stop changes cause problems with some start/stop calls in effects and offset. Run git submodule update

Use the originalEvent to grab properties in filter functions since they often won't have been copied to event. Mark a few current props in the main jQuery.event.props list as deprecated, they aren't supported across all browsers.

Conflicts:
	src/event.js
	test/unit/event.js

It was previously used in liveHandler for delegated events, but is now baked in to events.js. The signature is a strange one since it returns an array of matches, *not* a chainable jQuery object. I've marked it as deprecated.

The code is simplified by two things: 1) We don't care about optimizing the duplicate selectors case, and 2) `.is()` now handles positional selectors by looking for set membership, which eliminates the workaround that was being applied here. See https://github.com/jquery/jquery/commit/70e2e32e0eb03607ad0c8b7752dbd7747da47164 for that commit.

Thanks @cmcnulty for the pull and the patience!
