Complete overhaul of buildings:
- Small House replaced with Small Fort which is stronger and has a less boring shape.
- Large House replaced with Large Fort, which is stronger and has a less boring shape.
- Defended Airstrip strengthened, aircraft increased with Monocoque Contsruction and limited to T4+, since while cool and fitting the theme, it was too weak.
- Fortified Airstrip strengthened and aircraft increased with Monocoque Construction.
- Separate Missile Silo building replacing Guided Missile in T6 Large House.

Light Carrier has fewer aircraft to make it slightly cheaper.

Prefixed designs to avoid name clashes.

Fixed armour error on Carrier-Bombers-T3.

Updated airships for 1.2 and Heroes & Villains changes.
