fix some missing prereq declarations
reconcile plugin configs and documentation with each other

help ensure plugins are kept current
CPAN::Changes 0.23 is a little more relaxed
switch to Changes timestamps in UTC
Dist-Zilla-PluginBundle-Author-ETHER-0.018

          - now using [PromptIfStale] to ensure the plugin bundle is always
            the latest version, and all plugins are checked at release time
          - bring back [Test::CPAN::Changes], now that the spec has become a
            bit more reasonable (removed since v0.015)
          - Changes entries are now made with times in UTC, with a trailing
            'Z' rather than the CLDR 'ZZZZ' format code
