bugfix: advanced search

- date i18n : non standard date formating was totally wrong, full rewrite of date parsing (in getter and setter) relying on datepicker and datetimepicker parsers (they are awfull)
- date "now" button do no more close the criteria
- ie9 compat. : use history.replaceState only if available in order to prevent bugs with ie9
