Title: fix 11469: exclude margins from the properties that can't be negative.

By fixing [#11415](http://bugs.jquery.com/ticket/11415) you broke the ability to animate margins to negative values.
Someone else reported this problem: http://bugs.jquery.com/ticket/11469

Here's a patch that solves it without reverting completely the fix for #11415.
