PvP Combat reBalance mod 0.0.10 first release

A wide collection of changes to weapons, defenses and vehicles, tailored to improving the PvP (and to a lesser extent, PvE) experience. Major changes include:
- Weapon inventory stack sizes
- More movement speed for shotguns
- Slightly tougher cars
- Much softer tanks (in PvP)
- Majority of weapons no longer 1-shot players
- Damage types that excel against armor, players or biters.
- Balance fixes to fire and burning
- Armor module tweaks that make low tier options more viable
- And much more, tailored at smoothing the progression curve

Things that aren't changed:
- Item Recipes
- Technology
That may change down the line.
