Release v1.3.9

Changed

• Readiness diagnostics name the unavailable host event store and reactor in the health report and logs; the public health endpoints still answer with only a status word. (#162)
• Ante's specifications now run from the Debug application executable with --specifications; Release builds and published applications contain no specifications or test dependencies. (#189)

Fixed

• The lobby now restarts itself when its connection to a host inbox stays down longer than a configurable grace period (Ante:Health:HostInboxRecoveryGracePeriod, three minutes by default), instead of staying unready until someone restarts it. Short disconnects are tolerated. (#162)
