XML DOM .removeAttr() doesn't remove cased attributes

In case of an XML DOM the .removeAttr() function doesn't remove cased attributes. XML is case sensitive so attributes provided with uppercase should be handled accordingly.

jsFiddle with the reproduction:  http://jsfiddle.net/23w2d/

This problem seems to be introduced in 1.7, caused by an unconditioned .toLowerCase() in the removeAttr().

Pull request with the fix will be made after this ticket is created.

The problem is that there were no tests that would've caught the regression.

Fix #11547. toLowerCase not work good on XML attributes.

This was fixed to some extent in gh-724 but there were insufficient test cases. Removing the lowercase completely allows IE 6/7 to work properly since there you need an exact case match for attributes, even in HTML docs. More discussion and test cases in the comments on gh-724.
