Original description

Currently both the validation & metadata plugin apply styles to widgets
that are defined in a public css file and automatically imported.

This needs to be improved so that users can at least specify what style
names are used.

Possible Options:
Let users specify global styles names for the plugin.  E.g.
ValidationPlugin.defaults().registerStyleName(Severity.ERROR,
"someArbitraryClassNameTheUserWants");
Let binders that apply style take a CssResource in thier constructor. 
ValidationBinder validationBinder = new ValidationBinder(ValidationCss css);

Other ideas welcome.
