3rd Person camera, new Co-op dungeon, Control theme update

Fellow pilots!
Here goes one of the first improvements based on your feedbacks and suggestions.

First of all now arrow keys and ASWD behave differently. Arrows move the ship in their direction while ASWD is our usual control theme - acceleration and turns. You can switch the keys in settings.

Secondly we're announcing new game mode. Now you can play with 3rd Person camera! You will see the option when starting the game from Steam, or you can choose it in game settings.

Finally there is a new Co-op dungeon called The Slums. It's designed for 2-4 players and 15-20 minutes overall gameplay. Note that dungeon is still in development and have some minor issues.

- displaying map minimum and maximum player count in the list
- automatic resurrection for players when leaving the battleground
