Added prototype EDID support code.
Steve Revill authored
This should be considered beta-quality work-in-progress code that gives us a
new *command (ReadEDID) that attempts to read the list of supported display
mode information from a connected monitory and configure the system for it,
as if an MDF file had been loaded containing that information.

Admin:

Community testing is required for this feature. Please try replacing the
LoadModeFile line in your !Boot.Choices.Boot.PreDesk.Configure.Monitor
file with a line saying "ReadEDID". If you get a sensible looking list
of modes when the machine boots, then things should be OK. If you see an
error, please get in touch with ROOL on the "Bounties - ReadEDID" topic.
You'll clearly need to be running a ROM with this version of ScreenModes
in it!

Version 0.39. Tagged as 'ScrModes-0_39'
