Adjustable core position (#307)

* Made starting core position configurable and fixed tutorial sector core position

* Refactored classes to use a public int interface and a GridPoint2 as internal storage

* Battle missions now spawn the core at 50, 50 again

* Default player cores are now created at the first spawnpoint

* Manually fixed formatting which was not caught by auto formatter
