Remove SCANRES.COM 
SCANRES is a TSR providing support for varying the number of
scanlines (interrupt 0x10, service 0x1230) in DOSBox; DOSBox-X
supports that directly, so this TSR isn’t useful there.

This patch removes SCANRES.COM entirely.

.sp
This manual page briefly documents DOSBox\-X, an x86/DOS and PC98 emulator.
.sp
Options are listed below. Depending on the option, one or more may be specified.
.sp
The optional \fIFILE\fP argument should be a DOS executable or a directory.
If it is a DOS executable (.com .exe .bat), the program will run automatically.
If it is a directory, the directory specified will be mounted as the C:\(rs drive.
If the DOS executable requires parameters, enclose the command and it\(cqs parameters in quotes.
