Percona doesn't install, let's remove it and discuss sql servers in #3
Tweak apache config with vhost_alias, laravel need a htaccess fix but
will still need a manual chmod on the host as the vm can't modify the
permissions on the shared folder.
Chmod-ing should be mentionned on the README.
Finish cleaning modules, fixes #2. Percona is removed to allow a more flexible install, as discussed in #3
