Changes:

• added some sort of a forking license to the about screen
• most entities (like TNT or items) don't receive fall damage
• the hotbar can now be on the top of your screen, you can set that in the settings
• added autojump. It makes you jump when trying to enter a wall, but it's better than none, and you can always disable it.
• added a splash about how frustrating Zig is
• added a death screen, so that you can now respawn.
• grass is now animated
• TNT explosions now damage nearby entities (except for players in creative mode)
• added apples. They recover 2 hp and can drop from leaves

Plus a number of code improvements.
