Changes in gemfile
New versions of grape and grape-swagger seemed to have broken Hanlon.  Forced the older version
incorrect gemfile syntax
Missed comma
Merge pull request #302 from jcpowermac/tb/fix-grape-version

Resolved grape erors
Modified RHEL 6 kickstart
Removed ruby-runtime from kickstart.  Ruby package is not
included in the minimal CentOS 6.6 ISO, which cause an install error.
Merge branch 'tb/remove-ruby-rhel-model-299' of github.com:jcpowermac/Hanlon into tb/remove-ruby-rhel-model-299
