Support unset passwords with postgresql
Updated permissions for /etc/foreman/settings.yaml

Due to my umask of 077, I was unable to read the settings.yaml file.  By making sure the foreman group owns the file and the permissions allow the foreman group to read the file, I was able to use this module to start foreman.
Added Geppetto project file
Merge branch 'dev' of https://github.com/gwdg/puppet-foreman into dev
