Another big refactor, causing most of the functionality to work again + some extras. Full changelog:

- FPS Counter in top left corner, at all times. You can turn it off by commenting the code out in the main class.
- Other stations work as well, there wasn't any functionality in them though.
- You can now fly around if you enter the navigation station.
- Two games can connect and if the server starts the game, the connected client starts as well.
- FPS is now steady at 60 FPS (on my computer anyway). There was a huge performance problem with the DistributeReceivedPackets function.

Problems:
- The memory heap gets corrupted by the Enemy sync mechanic of the SendAndReceivePackets class. The problem lays in the deletion of Enemy classes. I did not figure this out yet. The compressing and uncompressing of packets with a Enemy vector should be redesigned probably.
