First cut approach

I'm experimenting with an approach to serialize NSAttributedString as text. The following markup generates the output beneath it:

hello <b style="background-color:blue; color:white;">world</b> WebKit.<br>
this is a <u>test</u> of attributed string.

[  0,  6]:[hello ]
          color: rgba(0.00, 0.00, 0.00, 1.00)
          font: "Times Roman" 16.00pt
[  6,  5]:[world]
          background-color: rgba(0.00, 0.00, 1.00, 1.00)
          color: rgba(1.00, 1.00, 1.00, 1.00)
          font: "Times Bold" 16.00pt
[ 11, 19]:[ WebKit.
this is a ]
          color: rgba(0.00, 0.00, 0.00, 1.00)
          font: "Times Roman" 16.00pt
[ 30, 26]:[test of attributed string.]
          color: rgba(0.00, 0.00, 0.00, 1.00)
          font: "Times Roman" 16.00pt
          Unknown NSUnderline:1

I might need to tweak the syntax a little but I think this is quite human-readable.

My current plan is put this serializer into DRT/WTR (probably shared through WebCore) and add a method like testRunner.dumpAttributedString(DOMRange) so that we can write layout tests to test attribute string generators.
