Thunder Under The Ice update.

Fixed toggle docking wiring, previous update disconnected terminal's toggle docking from AND components.

Turned on and set docking port's pump to -100.

UNBREACHABLE ARMOR
--------------------
Since Embrace The Abyss update, charybdis and endworms are able to breach alien walls and do AoE damage, thus it's impossible to block their attacks using only alien walls.

Thus, the sub has been redesigned focused on double hull protection along with addition of some layerings to prevent abyss creatures from attacking center part of the sub. Still, airlock and docking port can be breached normally since they are located in the outermost part of the sub.

To make it more balanced and prevent players from using the sub regularly, sub's reactor fuel consumption has been set to 0.600 (around twice of medium-large subs'). Fuel rods will deplete faster, so watch your fuel!
Fabricator and Deconstructor have also been removed to prevent players from manufacturing fuel rods and ammunitions.

--------------------
QoL
--------------------
Submarine layout total overhaul. More eye candies and interactable decorations.
Added crew quarters with tonics, alcohols, pipes, and instruments.
There are TVs too (for status and sonar monitor tho).

Added notifications via wifi directly into radio channel 0 chat to inform the crews in case of flood, fire, and reactor out of fuel.
Added auto-shutdown when the reactor is melting down.
*This wifi notification system is adopted from Teardrop's.

Railgun periscope can be switched faster using separated buttons. No more cycling railgun control.

Added Armory with shelves to store ammunitions.

Powered up all diving suit lockers and oxygen shelves.

Changed exploding coilgun ammos to piercing coilgun ammos.

The sub has been rebalanced to be comparable to vanilla subs:

- Pricing. Most reliable vanilla subs are set to be 2x of its auto-generated price. For this sub, price will be 5x of its auto-generated price, lol.

- Engine force. Most vanilla subs are designed with 3,000 - 13,000 hull/engine force ratio. Thus, this sub's engine force has been adjusted around that range. Power consumption was also set to be around 2x of its force.

- Pump speed. Vanilla pumps are set to be 600 (large pumps) and 100 (small pumps).

- Reactor. Fuel consumption of vanilla subs are 0.200 for small/handicapped subs and 0.250/0.300 for medium-large subs. However, this sub's reactor's fuel consumption has been adjusted to 0.600, lol.

- Weapons. No more multi-linked weapons. One weapon one loader. This is also as a future-proofing since there will be weapon switching in the next update.

- Loots. All containers in vanilla subs are set to be Auto-Filled. However, I think it will force players to do pointless inventory micromanagement, so I decided to give a standard set of loots but with its quantity reduced to 4 or 2.

- Oxygen tanks and battery cells. No vanilla subs have oxygen tanks and battery cells ready inside oxygen generators and charging docks.

Changed most labels and terminal commands into given templates so that the labels may be translated according to user's language setting (default: English).
However, since labels' spaces are limited, some words may not be read well.

Fixed bots' waypoints so that they wont get stuck when trying to weld leaks in the Airlock.

Added oxygen tank to Abyss Diving Suit (forgot to add one, ehe).

Added more materials to fabricate coilgun ammunition.

Restriction of access for some crews was lifted, everyone can access every part of the submarine, this is due to bots cannot repair/weld leaks in restricted areas.
However, for security purpose, added "lock door" button for captain quarter and medbay.

Edited for Embrace the Abyss update of Barotrauma:

- Enlarged gunnery compartment.
- Switched coilguns and railguns periscopes.
- Added more ammunition.
- Added Combat and Abyss Diving Suit.
- Added separate shell behind sub's engine to prevent major flooding when attacked from behind.
- Slight wiring enhancement and flooding measurement.

Added vent to central passageway. Air (oxygen%) was gradually decreasing before.

Thumbnail update with some sub optimizations.
