Support binding to style

[MichaelRFairhurst]

Also handle security for it.

Not sure why it isn't a part of dart:html in a usable way, and I'm not sure if angular expects to get a String or one of those SomeStyleThing classes.

There are two ways of binding to styles

[style.background-color]="'red'"

or

[ngStyle]="{'background-color': 'red', 'margin': 'solid 3px bue'}"

The classes CssStyleDeclarationBase and CssStyleDeclaration seem to list all style properties.

The properties in class CssStyleDeclaration have annotations like @JSName('backgroundColor'), but CssStyleDeclarationBase doesn't have the these annotations.
