Primitivus: major changes in SelectableText, menu can now be used with mouse, TabsContainer show wich tab is selected
- SelectableText is a WidgetWrap of urwid.Text, and manage attributes and complexe combination like urwid.Text (list of tuples (attribute,text))
- Menu now use a ColumnsRoller, and can't anymore be displayed on 2 rows, avoiding potential bug when display MenuBox
- Mouse can be used in menu. Right click on MenuBox make it disappear
- Tab container now display which tab is selected by putting a 'title' attribute on the corresponding button
/!\ as SelectableText is heavily used, there can be regressions
