Ticket #1663 (new enhancement)

Description

The content portlet shows documents of all languages, we propose to:

1.- Add a new boolean widget (and field) with id 'language_filtered' in the Content Portlet to "only show documents in the current language".

2.- Modify the script widget_portlet_content.pt to give getContentItems the parameter 'language_filtered'.

3.- In the script getContentItems.py, add the lines

if kw.get('language_filtered', False):
   query['Language']= context.translation_service.getSelectedLanguage()

before the statement:

brains = context.portal_catalog(**query)

Thank you very much.
