Update v.0.2 — Shivering Sky Steam update #234486

UI & Graphics: - Main menu - Graphics settings to adjust overall quality (access from the main menu) Turrets: - Customization of guns and sights (M2, M2x2, M3). Access from Main Menu - Modify Tab. - Decreased firerate for M2 to match the original value. Airplanes: - More realistic behavior in direct-fly mode. Collision avoidance is still active. - Increased accuracy for bomb trajectory prediction (time integration steps) - Altitude limit (decreases motor RPM). Not as a part of realism, but to prevent airplanes from climbing to outer space when dogfight scenario is running. Ships: - Changes in ship artillery: hit detection from collision to statistical to minimize the performance effect for high-RPM weapons. Large calibers and fused shells are using physical projectiles. - AI gunboats - fast and agile ships. Unlike destroyers, they take damage from MG.
