Merge #606

606: Cleanup Wasmer r=syrusakbary a=syrusakbary

This PR moves a few things around trying to make Wasmer more compelling to use:
* Two less directories on the root (`fuzz` is moved to the `lib/` folder, `media` is moved to `src/installer` folder)
* Improved README
* Moved `ARCHITECTURE.md` into the `docs` folder.
