Widescreen Support arrives!

• We've finally added widescreen support for (probably) all possible aspect ratios! Let us know if you still have issues with yours!
• Other minor bug fixes (dev features were previously still enabled, we have no idea how we let that slip through)

P.S.: Some content based on images (like level transitions or the main menu) will still have black borders, due to their static nature. The in-game experience will fully support widescreen, though!
