test_hardcore_respawn_parity.py copied test_locator_bar_parity.py's
build and run code; both now share locator.sides, and one-player
scripts run through locator.one_player.

A hardcore death offered another survival life. Vanilla's death screen
says Spectate in hardcore, and the server makes the respawned player a
spectator (ServerGamePacketListenerImpl.handleClientCommand). Do the
same on the server and in the in-frame world, and add a harness that
compares a hardcore respawn on a dedicated server with vanilla's.
