history:
versione 001005 = prima release
versione 010318 = automatizzata la definizione di nOp in selectOption()
versione 010423 = inserite le funzioni upperText() loverText() trimText() noBreakText(); modificato niceText()
versione 010524 = inserite le funzioni formReset(), formSubmit() formControlSubmit()
versione 020115 = inserita la funzione doPsw()
versione 020116 = inserita la funzione checkAll(), inserito il parametro action in formSubmit() formControlSubmit()
versione 020314 = corretta la funzione checkAll() con if nRec>0

n.b.: se si utilizzano versioni ³ 010318 vanno modificate tutte le chiamate a selectOption() v.001005
