Fixed syntax error in crowbar.yml

'@' is a reserved character in YAML, and needs to be quoted:

    http://yaml.org/spec/current.html#id2515596

otherwise rubygem-psych (as in ruby 1.9) complains about it and causes
barclamp_install.rb to exit.
Fixed missing colon in crowbar.yml

rubygem-psych (as in ruby 1.9) is stricter than older parsers
and does not tolerate this.
