Advanced search improvements (restore 2018-04-10 revisions : r5635..r5641)

* Add 'search_manual_submit' config parameter to manage auto-submit
* bugfixes
** date i18n is now handled (using two new options `datepicker.dateFormat` and `datepicker.timeFormat` computed from `AttributeDateTime::GetFormat()->ToDatePicker()`
** handling of `empty` `not empty` operator titles
*** it led to tohers bugfixes and a redesign of the `_computeTitle` (from overwriting to extension using ie `_computeBetweenDaysOperatorTitle`
*** some bug still remain, because autocomplete needs to been finished before checking on them
* Promote 'friendlyname' in the 'most popular' list
* bugfixes
** filters (criterions, enum and FK without autocomplete) now ignore accent on matching with user input
** this is done by using a pre-existing tool used only by the portal, so it was moved to the core (latinize.min.js)
* Integration with manual submit parameter on client side.
* bugfixes : history/breadcrumb had several c[menu] appended (one for each refresh)
* Fix various sanity bugs
