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)

org autocomplete 2/2 + fix string parsing + harmonize varnames: orgs is all, inst is big org, lab is small org
