Date ranges in faceted search go from 12PM to 12PM by default

Unlike in the advanced search, where date ranges are automatically adjusted to range from 00:00 to 23:59, the faceted search uses a non-configurable default time of 12:00 PM.

This is confusing for users, for example when following this scenario:

• Create a document during the afternoon
• Search for it by looking for "all documents created between today and today", without noticing the 12:00 PM in the fields
• The document won't be found

This problem could be fixed by making the nxu:inputDateTime tag configurable (currently the default time is hardcoded in org.nuxeo.ecm.platform.ui.web.tag.handler.InputDateTimeTagHandler). Then date_range_widget_template.xhtml could be configured to work just as in the advanced search.

Thanks
