README needs updating.

[enriquemanuel]

Currently the README.md has 2 options:

1. Sync from scratch
2. Sync from state

The scratch starts at version 4 and brings it over to version 6, but right now we are in version 8; can this be updated to include those steps? Also, can we sync from scratch from a different version?

Also, if we upgrade from State, the genesis file being pointed is wrong (the URL doesn't exist), but more importantly the process doesn't work. I just tried it and it fails and enters an error state and stops syncing.

Error trying to do state syncing

so my question would be, can the state sync be tested and corrected for version 8?

Hi @enriquemanuel -- great point -- I'll make links to gaia's state sync docs for v9 in #169
