tina: update most old jquery libs, replace bootstrap js by bootstrap-native js, fix bug in MS Edge on modal hiding and clean up some html

inst pie more agregated => more often informative + some tweaks for better display of piechart labels (but can do better)

fix print_scholar (matching+retrieval was limiting retrieved keywords) and factorize full_scholar_info cascade as a str param

php topbar: show current filters (exposed whoswho.popfilter and used it in js elements for print_directory)
