1.4.0: New event chains update

Hey guys! In this update, I added more content to play around with in the shape of event chains. Here is the list of all changes: [list] [*] A bunch of new events with 7 base variations. [*] Your station size now affects how fast pirates gather strength. [*] Fixed a bug that wouldn't hide items already bought by the traders from the player. [*] Fixed the bug where a large turret would fire smaller projectiles. [*] All projectiles now consume more ammo per shot. [*] Reduced ship order max margin back to 2.5x. [*] Fixed an issue where undocked trade ships wouldn't stop selling their items on the market if the game was loaded. [/list]
