Bug Fixes:
* Fixed enter battle/stop battle button having the wrong text sometimes.
* Fixed visualizing placing the core.
* Fixed placement of player ships after battle, they would sometimes spawn in the same spot.
Added:
* Ship linking, click the link tool below your ship (in build mode) to link the ship to another one, it will try to follow that ship instead of tracking down enemies.
* Range, click the range tool below your ship to set that ship's optimal range.
