This patch implements the "text-decoration-style" property parsing as specified
in CSS3 working draft, with "-webkit-" prefix. The specification can be found
here: http://dev.w3.org/csswg/css3-text/#text-decoration-style

Additionally, Mozilla implementation details can be found here:
https://developer.mozilla.org/en-US/docs/CSS/text-decoration-style

This is an individual task for bug 90958. Rendering support will be handled on a
different bug.
