FIX FIVE BUGS!

[NOTICE] In minecraft appeared five new bugs with sounds/music, background, textures, armor bar 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 plays minecraft, I've always seen errors with textures that had holes in textures.
