Small fix & optimization

FIxed hyperspace route from Murruun to Erithos - Enemy ships sometimes crashed without coming into contact with asteroids. Now it should work better. - Save option did not always appear correctly in escmenu - Improved aggro in surface enemies. Previously, some of them did not want to attack the player very much. They stood with their backs turned, as if preoccupied with more important things. - Crystal creatures in space have gained random speed. Some of them will now be able to catch up to the player's ship even with the best engine. - I dug through the code a bit and optimized it in a few places. I am correcting unnecessarily complex functions that I created in the first days of working on the game.
