Fixed one of the selector tests that was reporting incorrectly in browsers that actually supported type="search" inputs.

Made it so that appendTo, etc. return the inserted elements (thus using pushStack, as well). Fixes bugs #3966 and #4182.

Updated the show() tests to work without the use of jQuery.browser (the test suite now passes 100% in IE8).

Reorganized and disabled some of the height/width tests. Need to look in to better abornormal-padding/margin/border support at some point.

Switch to using createRange for element comparision instead of Array indexOf checks - thanks for the tip, Ioseb.

Brought back the compareDocumentPosition code. While it is redundant in Firefox it's much faster than using indexOf.

jquery event: closes #4033. e.currentTarget wasn't being enforced for native events (IE doesn't have it)

fix show issue in IE 6. "olddisplay" is sometimes undefined and IE 6 does not like setting style.display to undefined. also second for loop was mistakenly nested within the first for loop.

Added support for class selectors and class attribute selectors on XML documents. Fixes jQuery bug #4167.

Change the behavior of how :visible and :hidden work. :hidden is when an element is display none, a parent element is display none, or the element has a width of 0. :visible is when the element is not display none and all of its ancesotrs are not display none and its width is larger than 0. Fixes jQuery bugs #1349, #3265, and #3895.

Fixed a bug with certain + selectors failing (Fixes jQuery bug #4023). Also tweaked the + and > functions a little bit.

Make sure that [name=FOO] searches actually have the specified name (IE includes elements that have the ID, as well).

Added fixes for two different :not() bugs. One with p:not(p.foo) failing and another with a weird combination of multiple selectors and filters. Fixes jQuery bug #4101.

Provide a graceful failover for [name=foo] queries that are looking for non-input/iframe/form elements. Fixes jQuery bug #4081.

The compareDocumentPosition check was extraneous - indexOf works in all the other browsers that we need to support.
