widget for displaying previous orders.
Detailed changes :
- previous order is not a computed field, with its own custom widget that has been designed
according the new spec for widgets;
- useless wizards have been removed, and replaced by some server actions that perform the
same action with less code and views;
- removed deprecated or incomplete reporting;
- some renaming to follow the new specifications of module coding
