Same name and namespace in other branches

1. 7.2 radioactivity.field.inc \radioactivity_field_widget_form()

Implement hook_field_widget().

This widget displayed three text fields\, one each for red, green, and blue. However, the field type defines a single text column, rgb, which needs an HTML color spec. Define an element validate handler that converts our r, g, and b fields into a simulaed single 'rgb' form element.
