Prerelease 0 for the tetra armor addon

Here's a first prerelease of the armor addon for tetra, tetrawear! There's not a lot of content yet and some mechanics are missing, but it's at the point where I can start sharing it with you guys :). Here's a rundown of what's in it right now:

Agility & Energy

Empty armor slots and lighter armor (like a leather vest) provides agility. Agility increases the player energy which can be used to dodge by double tapping the movement keys. Empty armor slots provide 5 agility each which yields enough energy to dodge 3 times in a row.

Temperature

Tetrawear plays on the underlying temperature data available in vanilla biomes, but slightly tweaked so it's a bit colder at night. Temperature is split into 10 areas, those areas are considered freezing, cold, normal, hot or searing depending on the players temperature resistance. Health regeneration is increased in normal temperature, energy regeneration is reduced when cold or freezing and max energy is reduced in hot or searing temperatures.

I've been playing with /gamerule naturalGeneration false which makes hot or cold biomes rather dangerous.

Chest armor

Chest armor is the only modular armor piece available in this release. It has two major module slots: inner and outer, and one minor slot: arms. All vanilla armor enchantments should work for the major modules, generic enchantments go on the inner slot module and armor specific enchantments can be applied to the outer slot module.

The following modules are currently available:

• Harness: Inner slot module that provides integrity
• Elytra: Outer slot module that enables flight with a slight agility reduction, cannot be crafted as with vanilla elytras 
• Cuirass: Outer slot module that increases armor and hardness, reduces agility
• Vest: Outer slot module that increases armor, slightly reduces agility
• Poncho: Arm slot module that increases temperature resistance
• Bracer: Arm slot module that increases active armor (which isn't implemented yet)
• Shoulderguards: Arm slot module that increases armor, very slightly reduces agility

Next steps

With the current plan the next couple of steps would be:

• Add content for all armor slots
• Add more mechanics to the energy system, like mine with increased speed but drain energy, roll or dive with the elytra or sprint faster. Preferably with everything being heavily configurable.
• Make temperatures in some places more distinct, e.g. very hot in the nether or near freezing in the desert during the night. Cool down the player when wet and perhaps leave a "wet" effect on the player after they've been in water, with some modules making it go away faster.
• More textures and variants, e.g. scales, scrap metal and vent plates.

We should probably run a voting session for which one to go with first.

Poke me here or on discord if you have any questions, find any bugs or if you have feedback. Feel free to talk about this and share videos and screenshots, but please don't redistribute the jar :P
