Code cleanup.
	All struct members should be public (and removes warning)
	Implement "printhex" verb to print a/several sector(s) as
	hexadecimal values on console.
	Redeclaring ImageInfo inside of every plugin made the struct
	hidden, innaccesible and private, leaving the parent one as
	null forever. Corrected.
	Modified syntax
	Implement "decode" verb.
	Forgot header.
	Added function to convert space-terminated (' ', 0x20, ASCII)
	ASCII byte arrays to string.
	Added source documentation
	Preinitialize length for SpacePaddedToString().
	Change Console output to String output.
	Add function to write String output to Console.
	Implement SCSI INQUIRY command response decoding (and added
	adequate disk tag).
