Subject: [PATCH] Resend hull chunks to non-viewers after hull initialisation

Chunks encoded while the hull was filled as hidden contain obfuscated
blocks that become visible after initialize, and no block update is
generated for them. Reload the team's extend region for all players
that cannot see the hull.
