Up to [gforth] / gforth

Image starts at $100 for cross-compilation now. A NULL-reference
is really a reference to address 0 and NIL is 0.
In the kernel image-header to get the headers address.
Image loading is only changed minimal: The stuff with fixed
addressed images is thrown out, because every image is relocatable.
No header change. Old images should work.
