Update v0.3 (Gamepad support)

Change log:

• GAMEPAD SUPPORT!
• BOSS TEMPLE! - every 5 levels you'll face the boss in his temple. Prepare your self (I'm serious, he's kind imbalanced)
• HIDEOUT - a new area where you can take a break after the boss fight
• Weapon balance
• UI improvement
• Controls - to see what keys/buttons are used go to Settings->Controls
• SFX lags fix(actualy a workaround, hope it's better now)
