[Oberon] 1G RAM in Emulated RISC Oberon

I have modified the oberon-risc-emu a little bit more so that I can have a large heap and
more space for modules.
Now I have a 1GB of RAM in my RISC V5 Oberon system.
I have updated my patches for the emulator but I expect to
discard my patches as Peter finds cleaner ways to incorporate the functionality.
Thank you Peter for the alternate framebuffer merging!
Like we said elsewhere, I think its important to keep backwards compatibility with the FPGA risc
image so that we can have a coherent new system. Peter's changes nicely maintain compatibility.
