Fully automate manual mode for shared hosting

@destruktomatik I’m positive, I’m pointing to the correct directory. When I tried to the acme-tiny client, I was able to get certs signed in my vagrant env and the sshfs mount. Trying to use the Let’s Encrypt client succeeded today. Unfortunately, I can’t pinpoint my fix. Since my last attempt, I did a git pull to update the Let’s Encrypt code and my vagrant box (ubuntu/trusty64) was updated.
