Solve remaining text without i18N
Adding date format support from user locale

The date/time pattern to show DateTime is externalized in i18N files,
see on message_xx.properties to set date.formatter.display and
time.formatter.display as date pattern. See documentation at
http://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html
Adding i18n support on jquery datepicker

Not sure this is the best way to do that, an other one would be to have
an hiden div lang set from the request.
