MAX-10 fix (#133)

* MAX-10 fix

Additional delay for IRQ on VSYNC High to Low transition.  MAX-10 uses
the IRQ to check PIA0 for keyboard and mouse button presses but was
not catching the interupts soon enough.  CPUAssertInterupt(IRQ,1)
changed to CPUAssertInterupt(IRQ,4).

* Update ReleaseNotes

* Fix directinput version warning.

Move DIRECTINPUT_VERSION define from joystickinput.c to joystickinput.h

* Updated Release Notes again.

Include fixed issue with some 6309 register instructions.
