Rename Vool to Sol

Browse Source 
Simple is really the descriptive name for the layer
Sure, it is "virtual" but that is not as important as the fact that it is simple (or simplified)
Also objct (based really) is better, since orientated implies it is a little like that, but only orientated, not really it. Sol only has objects, nothing else
Just cause i was renaming anyway

# SlotMachine
This layer sits between the language layer (vool) and the risc machine layer.
It is meant to make the transition (between vool and risc) easier to understand.

Previous efforts were doing the transition without an intermediate layer. But while
this was possible, it was more difficult than need be, and so we go to the old saying

Sol has no memory, it has objects and they just are. Risc on the other hand has only registers
and memory. Data can only move to/from/between registers, ie not from memory to memory.
While Risc knows about objects, it deals in machine words.

The *essential* step from sol to risc, is the one from a language to a machine. From statements
that hang in the air, to an instruction set.
So to put a layer in the middle of those two, SlotMachine will be:
