Large update, balancing, removed some items

Added a new map that blocks the naval base from being entered on foot.

Added an rcon restart command that has a countdown timer parameter.

A lot of code that isn't required in this gamemode that was carried over
from the freeroam script has been removed now. Some useless items were
removed (Warning, this has re-ordered the item type definition values)

Entitiy loading for specific areas of the map have been moved to
separate files.

Added an auto save feature that saves all player data, vehicle data and
safebox data every 5 minutes.

Fixed an exploitable bug that allowed players to find other players
positions when they were offline by logging into their account, clicking
leave then pressing Tab to remove the black screen cover. Your position
is now only set when you actually log in successfully.

Removed a lot of debug prints.

Added a duty state admins can be in, while in this state they cannot use
many gameplay mechanics such as items or inventory but can teleport to
players. They are put back to their original position upon exiting duty
mode.

The OnPlayerDeath hook system has been removed, it was originally there
to properly detect who killed who but that's not really required in this
gamemode.

All items are properly dropped on death.

Cleaned up the OnPlayerCommandText code and added a new return value for
the admin duty system (6).

Improved the ladder code. It now has height boundaries so you can't
enter a ladder more than 2 meters above/below it's bounds. And the
hooking is done properly now.

Turrets have been removed due to a fatal crash bug that is still
unknown.

Zipline code has been much improved, it now uses a timer instead of
OnPlayerUpdate to update velocity in order to maintain a more constant
interval between updates. And it now works on lagging players a little
better now as the Z velocity is increased slightly if they start to drop
too far from the line segment.

Most of the tools have been cleaned up to properly stop updates and
allow the entering of vehicles without having to hold the F/Enter key.

Electro-Armour has been removed, it was a silly idea! Awaiting a new
item to replace it. Canisters have also been removed, they were useless
items that caused crashes.

Commands files have been moved to a folder and renamed to better suit
their role names (and to avoid an annoying include bug with Pawn)

Loot has been tweaked a lot to better balance the spawn rates of
high-end weapons and fix some items that were too common.
