.SCP files usage in WinUAE

[keirf]

Well I don't have an SCP which is why I need a couple of known-good images to work with.

Making a library with the CAPS API is an interesting possibility. It doesn't allow for write support though. And crowbarring into the existing CAPS library to make a dual-format library is bound to piss off the SPS guys, and I respect their work too much to do that.
