fix .latest: subsequent "ln" calls were following the existing link and creating in the wrong place
add [EnsurePrereqsInstalled]
split Dist::Zilla::Plugin::BlockRelease out into its own distribution
-StopWords adds *no* extra value here or pretty much anywhere
Dist-Zilla-PluginBundle-Author-ETHER-0.060

          - fix adjustment of existing .latest symlink at build time
          - added use of [EnsurePrereqsInstalled], to check ; authordeps are
            satisfied
          - Dist::Zilla::Plugin::BlockRelease (used by airplane mode) has been
            broken out into its own distribution
          - removed unnecessary use of StopWords in this dist, dists being
            built and dists being minted
