Initial import of the first (extremely early) functional version.

It doesn't look like much, but it's functional ;-)

It can inject distribution pokémon into gen 1 and gen 2 original
cartridges and inject the GS ball in Pokémon Crystal.

That's it. But that was the minimal feature set I had in mind for the
project. In the Readme.md you can find the ideas I have for expanding
the project.

But the first priority is the UI, because it really looks bad right now.
(as I was mostly focused on building blocks and transfer pak
functionality. Not on making it looks good)
