#8150 - When removing the width and height attributes in IE6/7, setting to "" actually sets to 0 instead of auto

- Having fixed this automatically with the use of removeAttribute in browsers that support it, this will fix it for IE6/7 as well.

- This has no effect on width/height styles set elsewhere( test added to removeAttr )

- With this addition, I need to call attr in removeAttr for IE6/7, which means boolean calls like .attr("checked", "") will no longer remove the attribute, which I think is fine.  .attr("checked", false) will still remove.  If I had left it, it would have gone in an infinite loop since setting to empty string is the only way to remove it in these browsers.

- The hrefNormalized hooks were returning null if they weren't present.  Added the null check to the getter.

- Now that the style support fails in IE8 as well due to uppercasing everything, no need to have style included with the hrefNormalized hooks
