-Added the "Extended Quest Mode" sandbox option, in which you have to craft the antenna to start the quest.. the first step to make more complex and long playthroughs.
-Added the antenna, a new craftable item which allow you to contact headquarter and request a new extraction zone or to start the quest if "Extended Quest Mode" sandbox option is active. In future this item and this mechanic will be used to allow you to choose extraction zones not in vanilla maps.
-Added a new extraction zone in Rosewood Penitentiary. (be well prepared..)

-If a random extraction zone is chosen now you can customize which zones include in the random pick list. (If a fixed extraction zone is selected this parameter is ignored)
-Tweaks to spawn logic to alleviate the quirks of the AI

-Added a sandbox option that allows you to set the number of days to wait before the radio signal needed to call the helicopter becomes active.
After the signal is active, the deadline time (if set) will start , in this time it will be possible to call the helicopter using the walkie talkie.
-Added the name of the extraction point in the extraction tracker gui and enlarged some fonts for better readability.

-[MULTIPLAYER] Fixed a bug that leads to the change of the extraction area at each login if the random extraction point has been chosen.
(Of course if you choose a random extraction point in the server sandbox each player will have a different extraction point, so to share the same extraction point you need to choose a fixed one)
-[MULTIPLAYER] Fixed spawn of zombie only visible to one client
-[MULTIPLAYER] Fixed weather only clientside
-[MULTIPLAYER] Fixed Helicopter sounds audible only to the client that request the extraction

-Increased the maximum duration of the extraction event from 9 to 48 hours (however for an optimal experience the recommended value is still 3/4 hours)
-Since it was requested i have added 3 new extraction points not in Louisville: 2 in Muldraugh and 1 in March Ridge
-Added the "Confined Mode" option in sandbox, if selected you must stay near (about 30m currently) the extraction point during the entire duration of the extraction event.. if you go too far you need to restart the event.
-Spawn rate tweaks and small optimizations

Hopefully the extraction zone changing bug is fixed, let me know!
