Title: add single quoted literal

Added single quoted string literal which behaves like ruby's single quote literal.
This idea was introduced at https://github.com/fluent/fluentd/issues/435#issuecomment-56919111

Please note that this is effective only for :string datatype, not effective inside array or hash yet.
