Subject: other frequencies verified

Corrected Diet gogo h6280 clock so that it behaves correctly with
Charles Macdonald fix to the cpu core.
Verified anc corrected frequencies and pin 7 okim6295 on the following
games:
The new zealand story (3 z80 version), Trio The punch, Vandyke,
paradise.c games, Downtown, Shaolin's Road and Twins.
Updated Xtal.h with 1.056mhz resonator from Trio the punch
