filetext.* Aggiunto supporto per saltare le prime _skiplines di un file

form.cpp    Rimodernato uso della clessidra:
            niente piu' main_app().begin_wait(); e main_app().end_wait();
            ma solo e semplicemente TWait_cursor hourglass;
isam.*      Aggiunto metodo TBaseisamfile::open_ex che non da' errore
            fatale se non puo' aprire un file, bensi' ritorna un codice
            d'errore appropriato.
            Aggiunto parametro zap alla TSystemisamfile::pack_file
            che permette di azzerare completamente i record di un file
lffiles.h   Aggiunta #define LF_EXTERNAL 1000 per indicare la base
            dei numeri logici dei file dbf esterni
