Update 0.3 Kart Racer and 2nd Edition

Welcome to the next update of Exploration Playground

Changelog:
- Added a new feature (hence the version name) called Kart Racer mode. Press 5 to enter KR Mode. Press 4 to return to normal
- Changed resolution from 1024x768 to 1280x720
- Sized down the cake model, along with its barrier
- Added more barriers for the swing
- Increased Gravity. I still need to fix the velocity so you don't snap down when falling off a platform.
- Changed the position of the lighting for a more "Twilight" theme. v0.2 had it as more of a sunrise than twilight.
- Stretched the green block. This has now been renamed to the "Green Screen"
- Raised the slope
- Fixed the main menu screen (Exclusive to 2nd Edition)
- Textures have changed (Exclusive to 2nd Edition). I did not do anything apart from changing the menu, and that is on a different scene. I don't know what the hell happened, but it fixed it a bit

Second Edition
The only reason that 2nd Edition exists is that while building the game, the main menu wasn't fixed in the original. This and the textures were the only thing that changed in 2nd Edition. I decided to give the player the option to play either 1st Edition or 2nd Edition (for anyone who would be annoyed by the menu idk)

Just have fun. Not a massive difference between 1st and 2nd Edition. Stay Safe and Have Fun :)
