	Legenda:
	WINNAME			nome div della lista di voci
	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
