Bug fix for a crash on extremely long Patrols.

Sped up saving convoy data; as a result, ship names are no longer shown in Patrol summaries. Escorts can no longer shell you if you are hidden behind a transport. Checks to see if you actually made the leaderboard before asking if you want to post high score. When inside a "convoy spotted" circle: 1) encounter comes much more quickly. 2) Guarantee larger convoy and better whale odds. Added loading screen. Versioned leaderboards. Tightened up all ship bounding boxes to reduce “hovering fires” effect. Patrol Mode Redesigned: 1) Removed 30-day time limit 2) Slowed time passage 3) Added fuel gauge/consumption. Fuel consumed while moving; 10% consumption while stationary. 4) Resupply also refuels (25% of capacity). 5) Fuel range radius displayed as red ring on map. 6) Warn player when fuel is below range to base + 10%. 7) Reduced chance (10%) of convoy encounter when stationary. 8) Return to base = patrol end. 9) Run out of fuel = Roll for rescue, with better odds the closer you are to base. Bug fix: Detonated torpedoes that haven’t yet despawned can no longer be spotted.

Added 16x time scale. Added encounter timer. Made Time scale buttons larger. Notify when depth charges splash. Sim mode: Start further from Convoy. Sim mode: Hide notifications that you shouldn’t know (torpedo/sub/periscope spotted). Torpedoes don’t always get spotted by enemy (scales with difficulty). Added Custom game mode.

Added separate difficulty unlock progressions for Single Mission and Patrol modes. Must sink at least one ship to advance difficulties (both Patrol and Single Mission). Shows device ID in "About" window. Thermocline depth/thickness is now randomized on each encounter. Thermocline is now displayed on depth gauge.

Targeted ship's chart view marker and tracking info now disappear when ship leaves perception range. Retracted periscope can no longer be damaged by enemy ship collisions when sub is at 10 meters or below.
