Issue 774, 879, 981: DOMita style issues

Issue 774: Domita cross-browser style assignment
    A way to get and set the "float" style property - IE uses
    "styleFloat", others use "cssFloat", we normalize as
    "Dom.getStyle(element, 'float')

Issue 879: Add a function to the autogenerated css-defs.js that maps between
CSS property names and DOM2 Style node property names
    In domita.js (and domita_test.html) we use a horrible hack
      cssPropertyName.replace(
          /-([a-z])/g,
          function (_, ltr) { return ltr.toUpperCase(); });
    to map between CSS property names (e.g. font-size,
    background-color) and DOM2 CSS Style Node names.
    Consolidate this code and extend it to handle exceptions to the
    rule such as float<->cssFloat (see
    http://beradrian.wordpress.com/tag/cssfloat/ )

Issue 981: fake style object needs getPropertyValue
    From http://www.w3.org/TR/DOM-Level-2-Style/css.html

    getPropertyValue
        Used to retrieve the value of a CSS property if it has been
        explicitly set within this declaration block.

LGTM.

CssPropertyPatterns.propertyNameToDom2Property(Name.css("list-style-image")));
I think this line breaks the 100-char limit for Java.
