plugin system, first draft:
- widgets are now handled with plugins, ContactList and WidgetSelector have been changed to be pluggins
- everything in PLUGIN_INFO (including PLUGIN_INFO itself) is optional. Best guess is used if a value is missing
- WidgetsHandler use default widget from plugins, which is WidgetSelector for now
- PLUGIN_INFO is used in the same way as for backed plugins, with (for now) following possible keys:
- "name": human readable name
- "description": long description of what widget do
- "import_name": unique short name used as reference for import
- "main": main class name
- "factory": callback used to instanciate a widget (see Cagou._defaultFactory)
- "kv_file": path to the kv language file to load (same filename with ".kv" will be used if key is not found)
other data should be added quickly, as a path to a file used as icon
- host.getPluggedWidgets can be used to find loaded widgets. except_cls can be used to excluse a class (self.__class__ usually)
- fixed host.switchWidget when old widget is already a CagouWidget
- CagouWidget header new display the available widgets
