Better Pathfinding

Features:

Icarus now tries to jump or fly over obstacles when stuck
When the target location is set far away on the planet Icarus will automatically fly instead of walk to the target location
- Only activates when Icarus' core energy is not low and the thruster is unlocked
You can right-click on a location in planet view to pathfind to there
(Needs to be enabled in the config) Icarus auto-lands at the target location when pathfinding was started while flying
(Needs to be enabled in the config) Icarus auto-pathfinds to and mines coal to restock his reactor when on low power
