 #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

IE8 testing for lowercasing the css properties on retrieving style; had assumed the style support check failed in IE8, which it now does

Per request, here is an simple git for dummies quick sheet, with some
useful commands.

Adds a default falsy value for focusinBubbles + minor style consistency regarding test expression in support map initialization.

Applies exception in Style Guidelines regarding objects and functions when they are the last argument of a function call.

Fixes #8722. Remove try/catch used by #3533 to fix the IE Table Colon Blow bug, and instead check for colon in the event name. Thanks to daguej for scoping this out -- a colonoscopy you might say.

Create jQuery.holdReady(true/false) method to encapsulate jQuery.readyWait++ / jQuery.ready(true) logic. Fix problem where jQuery.ready may trigger twice, causing the (unsupported) document.onready to run twice. Fixes #8803 .

Rewrite of the support module. We use a temporary body element in order not to have to wait for the document to be ready for boxModel-related support tests.

Rewrite of globalEval. Uses window.execScript or window.eval with a trick to ensure proper context. Unit tests added.

Adds fn.promise as a mean to observe the completion of animations on a set of elements. Only queued animations are handled for now, non-queued animations support coming soon. Effects unit tests updated to test the feature (needs more testing though).
