Flotsam

The key resource flotsam added. Collect Flotsam to make more buildings. Added store building to store more flotsam. As you approach flotsam, the hook will drop automatically.

The new dial on the controller tells you how much Flotsam you have as a percentage. If you're full, the hook won't drop. Add more stores! If a store has flotsam and is destroyed or removed then the flotsam it is holding is lost!

To keep things easier while I work out balance, spawn and enemy with F4. This is only temporary.
