The main goal of this commit is to simplify, uniformize and remove
unused props. The props removed are : options, attrs and className.
The readonly prop is uniformized with the one in the fields api. It will
now allow the use of readonly as modifiers on the widgets, as it's
already the case on fields.
This commit also uniformize the parseWidgetNode with the parseFieldNode,
the widget doesn't receive on props the rawNode anymore but a widgetInfo
as is the case for the fields.
