Fix a bug with sounds (music) with turning on/off, and make "F" button in inventory like 1,2,3...9 to choose slot in inventory..

[NOTICE] In minecraft appeared four new bugs with sounds/music, background, textures and inventory.

[SOUND / MUSIC BUG] Minecraft had a bug with music what plays on the other, but when I turn off the music, only one turns off and the second plays without interruption.
[TEXTURE BUG] When I play minecraft, I've always seen errors with textures that had holes in textures.
[BACKGROUND BUG] When I download my world (server), my background and font get worse when I generate new (old) world, with a monitor size of 1920x1080.
[INVENTORY BUG] Make "F" button to choose a slot in inventory, like: 1,2,3,4,5...9.
