Update V0.3.23

Navigation system Captains! We are glad to present you a new feature - Navigation system. It replaced the old World Map but retained its basic functions. This system will show your ships, airships and strekolets in flight, regardless of their location. Other characters' aircraft are shown within a 30-mile radius of your location. The functionality of the system will be expanded later.

Skills Now when you cancel the learning of a skill, money spent on learning are refunded in proportion to the remaining time. The less time is left, the less money will be returned to the character's account.
