WidgetDrawInterface impl. to draw widgets from file definitions

This adds FileDefinitionWidgetDraw which extends the
WidgetDrawInterface and is responsible to draw the widgets from
the definition gathered from an external file. The file must be
(currently) in the user folder named definition.xml.
It instantiates the WidgetDefinitionReader to get the definitions
and sets the style colors when updateSettings is called. Later
more definitions will be implemented.
