Ships reworked

Made by Yandersen for Stellaris v1. 6 All ships rebalanced, 4 new ship sizes added; resulting line looks like: Corvette, 1 Naval cap, 300 HP; Destroyer, 2 Naval cap, 600 HP; Cruiser, 4 Naval cap, 1200 HP; Battleship, 8 Naval cap, 2400 HP; Dreadnought, 16 Naval cap, 4800 HP; Titan, 32 Naval cap, 9600 HP; Flagship, 64 Naval cap, 19200 HP; Battlestar, 128 Naval cap, 38400 HP. Each spaceport level now grants new ship size and Assembly Yard tech with the exception of Flagships and Battlestars (independently researched, spaceport 6 requirement, no dedicated Assembly Yards). Military stations rebalanced, 3 new ones added; resulting line looks like: Defense Platform, 4000 HP; Defense Station, 8000 HP; Fortress, 16000 HP; Bulwark, 32000 HP; Bastion, 64000 HP; Citadel, 128000 HP. All weapons rebalanced, mechanics changed (dmg, CD, range, shield and armor penetrations for various weapon types). Crucial changes: PD, torpedo and XL weapon slots has been transformed into 3 new weapon tiers for new ships; 'new' weapon slot tiers are "D", "T" and "F" following "S", "M", "L"; those 'new' weapon slots are available on ship sizes above Battleships; Point Defenses are general "S" slot instead of "P"; Torpedoes available at general "M" slot and above; Extra-Large player-available weapons now start at "D" weapon slot types; special mechanics (blank range, firing arc) has been removed since those weapons become turret-mount; Disruptors now unlock only if Energy Siphon critter weapon reverse-engineered (this one buffed to be useful); Arc Emitters now unlock only if Arc Lightning critter weapon reverse-engineered (this one buffed to be useful). Utility slots rebalanced to accommodate for larger hull sizes: now 1 medium size device equal in properties to 8 small-size devices of the same type; consequently, 1 large-size utility device equal in properties to 64 small-size devices of the same type; all ship sections configurations and utility devices' properties has been rebalanced accordingly t
