Hi

When using WinUAE CPU in CE mode, interrupts (in that case FDC 
interrupt) were not always correctly handled.

After discussing with Tony, this is because the way interrupts are 
handled at the moment at Hatari level is not how WinUAE's CE mode 
expects the ipl signal to be updated.

A fix has been added to keep it working anyway, but integration of CE 
mode in Hatari is still a work in progress.

With this, the demo runs completely (that's also because it doesn't use 
too many effect like plasma or overscan which are not correct yet in all 
cases in CE mode)
