Grid - ComponentRenderer - allow adding click listeners

Situation

We use ComponentRenderer in a grid to render custom components in a cell (f.e. an Image followed by a Label wrapped in a HorizontalLayout).

Problem

The only problem is the grid allows selection but the custom components do not 'forward' the selection to the grid. I tried doing this without changes to the vaadin framework but did not succeed. The problem was getting the clicked row when adding a context click listener to the custom component.

Proposed solution

This could be solved but allowing click listeners on the ComponentRenderer where the click event has the item of the row (like the ButtonRenderer has f.e.), so basically letting ComponentRenderer(Connector) extend from ClickableRenderer(Connector).

FYI: I forked the vaadin-framework ,worked on this and will submit a Pull request.

Start by comparing ComponentRenderer and ComponentRendererConnector with ClickableRenderer and ClickableRendererConnector, using ButtonRenderer as the example for row-aware click events. Trace how Grid selection and context clicks reach custom components, then verify that ComponentRenderer click events expose the rendered row item and forward selection appropriately.
