/* 

Questo script legge le versioni piu' recenti della pagina corrente
usando le API di Mediawiki, e le mette in un box sulla sinistra, sopra
al box "navigazione", dopo la pressione di un pulsante.<br/>
Nel box vengono elencati gli utenti che hanno modificato la pagina
(con un link al paragrafo modificato).<br/>
Prima di ogni nome viene inserita l'ora della modifica che, se cliccata, apre
una finestra in cima alla pagina mostrando le modifiche rispetto alla
versione precedente.<br/>
Fermandosi con il cursore un paio di secondi sul nome dell'utente, verra' 
mostrato in un tooltip l'oggetto della modifica.
