Update to 2.4.1
    
    - New upstream release 2.4.1
      - Merged the pull-request #13, which fixed an issue where the behavior of
        role method confliction was different from Moose; this change might affect
        your existing code so the major version has incremented (see
        t/030_roles/role_conflict_and_inheritance.t for details)
      - Dropped 5.6.2 support
      - Migrated to Minilla
      - Fixed #16 (Inconsistent coercion/validation of Bool type)
      - Fixed #17 (Memory leak in applying roles to instances)
    - Classify buildreqs by usage
    - Switch to Module::Build flow
    - Make %files list more explicit
