Thunder Under The Ice update.

--------------------
MOVING HANGAR HATCH
--------------------
Reconquista's hangar has been equipped with moving hatch to protect stationed drones. The hatch can be opened/closed using Toggle Hangar button in the command room. However, the hatch is set to be no-AI target to prevent crawlers and mudraptors latching on top of the shell. These latching creatures tend to get stuck when the hangar is opening, then preventing the hangar to be reclosed, breaking the system.
Fortunately, medium-sized creatures like hammerheads and molochs can damage the hatch and shell normally without breaking the hatch's system.

--------------------
NEW DRONES
--------------------
Auras and Bettas have been depreciated, they were hardly useful in campaign and multiplayer sessions. Three small newly-designed drones were assigned with single coilgun and shuttle control so that players can use them either as drones or shuttles (similar to Teardrop's). With their small size, the drones can be used in exploration or caving. Unfortunately, it also causes the drones susceptible to major flooding in case of creatures attack.

--------------------
QoL
--------------------
Submarine layout total overhaul. More eye candies and interactable decorations.
Added crew quarters with tonics, alcohols, pipes, and instruments.
Added berthing compartment and separate lockers with their own keys (id cards). Master key is captain's id.
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.

Powered up all diving suit lockers and oxygen shelves.

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 2x of its auto-generated price + 1,000 marks for each shuttle.

- 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. So, reactor's fuel consumption has been adjusted to that number.

- 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. All ammunitions were also changed to standard coilgun and railgun ammos.

- 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.

Fixed bots' waypoints. Auto-generated waypoints made the bots couldn't go in/out of the sub when docked to an outpost.

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.

Added Mineral Scanner.

Fixed Backup Power's Signal Check, it should be able to be used now.

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.

Added Combat Diving Suits and more materials.

Thumbnail update with some sub optimizations.

Fixed sub and shuttles' waypoints, the bots can now travel between them accordingly.
