Added tweaks and fixed misc. bugs, inlcuding:

• Metered sprint
• Shooting through drops
• Changed drop rate
• Full controller support for menu/selection navigation
• Tweaked UI and explosions
• Changed camera settings
• Audio overlap issues in boss cutscene

I also gave in and changed the base shooting attack to right trigger on the gamepad since it feels more modern and natural. Additionally, we added the SPECIAL LASER CANNON, which can be charged by defeating enemies. Thanks to my friend August for the suggestion.
