	WINCLASS			classe CSS associata
	ITEMNAME			suffisso dei div degli elementi
	ITEMCLASS			classe CSS dei div non selezionati
	ITEMCLASSSEL		classe CSS dei div selezionati
	VALUEOK(_RGB)		colore dello sfondo in caso di valore
						presente in lista
	VALUEERR(_RGB)		colore dello sfondo in caso di errore
	INPDISABLED(_RGB)	colore sfondo campo disabilitato
	WIDTH				larghezza div dei suggerimenti
	HEIGHT_MIN			altezza minima div dei suggerimenti
	HEIGHT_MAX			altezza massima div dei suggerimenti
	DELAY           			ritardo nell'autocomplete su BACKSPACE e DEL
							-1 = disabilitato
	MINACT          			numero minimo di caratteri di attivazione
	RESNUM          			numero massimo di risultati in lista
							-1 = illimitato
