refactor field's value retreiving from the widget (eg 'display value' concept):
* kill field's display_value method, since getting value specified in a previous
post or in req.form should be the widget responsibility (the widget nows what
inputs to display, not the field)
* new typed_value / format_value on widgets, mainly to ease overriding
