Special Weapons are now available!!

I've added unique special weapons that can be purchased from the upgrade store for each of the ships. They have a high cooldown (60 seconds), but can really clear out a lot of enemies.

I've also reworked the boss camera, I've had feedback that it gets too zoomed out and makes it hard to see/play. So now I revert back to the normal camera if you get too far away, and put up an orange arrow pointing to the boss. If you get closer, it will go back to trying to keep the boss in frame. Let me know what you think!
