0.2.1 - Grid<MyBean> columns in design file

Recommended way to add columns to a vaadin-grid element is to add a custom attribute data-columns and then provide a space-separated list of property names, for example:

<vaadin-grid data-columns="property anotherProperty someOtherProperty"></vaadin-grid>

Those properties will be called with server-side Grid.addColumn(propertyName).

0.2 - Grid<MyBean> now supported

In addition to string-based properties there is an extra configurator that makes sure Grid<MyBean> gets MyBean.class (so that grid.addColumn("property") can be used).

0.1 - Initial

Experimental release. Works, but with known limitations.
