Redid the way SCSI and ATAPI devices are handled; Slight timings change in the NCR 5380; Devices are now closed by device_close_all() in the reverse order of the one in which they were started; Slight changes to some code in win/; Added the WM_HARDRESET and WM_SHUTDOWN window messages for configuration manager purposes.
