updated readme with clearer ssh-agent instructions.
changed the git.latest to git.present for the drupal-highwire and drupal-webroot repositories. changed the revision from 'dev' to 'stable'. the sql file is now loaded from the /opt/public shared dir and only if the lock file doesn't exist
cleaned up vagrant file. removed chef provisioning. removed old/broken comments. re-enabled the file checking for sql and vpn files
really scrubbed the vagrant file. shifted a lot of options to the top of the file. added an option to make the vpn optional - this is reflected in the system salt state file, too. reverted change to git.latest -> git.present because git.present doesnt really do what we want and git.latest doesnt appear to be destructive. made the git ignore file ignore everything in the public dir
