respawn point fixed

small bug

Nothing changed except the name.
Thank LoboLupus for telling me the problem about server.
Thank Dongfangfang for the last update's content.

After 10 mins,zombies in the prison floor will spawn outside everywhere instead of stopping spawn.So BREAK THE SPAWN POINT is necessary.
Add four zombie spawn points in the bottom.
Water in the bottom won't hurt zombies any more.

Extended prison floor's zombie spawn time,now you can try single player.But I still died 3 times to get through it :)

Added some furniture for the owner of prison.
Canceled all the invincible points except those in the first spawn point.
Adjusted zombie density to keep the consistent difficulty.
Turned some random items into fixed items in case of your BAD LUCK.
Underground warehouse is no longer safe,fire will burn there during the siege.

Teleport now works.
Gunlockers have guns now.

Added Necessary Instructions.
Reduced the Zombie Density In the End.
