CC style handled incorrectly and does not work with maven-release-plugin 3.0.0-M5 #16

With the release plugin 3.0.0-M5 the plugin does not work due getEnvironment() got deprecated.
As mentioned in issue #7 the version handling skips one version due the snapshot version after release is not used.
The breaking change type is handled differently than it is described on the reference site and the footer based way is not supported.
