Up to [gforth] / gforth

changed image file format:
   now every stack has its own size spec in the image
   size changes through the command line are passed to the image (and
	saved with savesystem)
   added a checksum to protect against incompatible binary/image combinations
	(e.g., direct threaded binary with indirect threaded image)
   the preamble specifies an interpreter and is propagated by save-system
