    feat (release) travis_release now creates -rc version
    
    our travis_release task now creates an rc version.
    This way, the master branch will always have a version that will make it
    clear to our users that it's not released. It will never conflict with
    a released version, and will always compare smaller than its actual
    release (1.2.3-pre < 1.2.3).
    
    This also hides the module:* tasks until they are actually used by the
    travis_release task.
    Further, module:tag is executed idempotently
