Fixed a few things

+Fixed it so blocks being used for players models would be positioned
correctly.

+2nd third-person view camera distance now adjusts to distance between
player and the block being looked at. (need to find a way to get normal
third-person to do that now)

+The "Sky" no longer disappears when you go past (Level.Height + 10)

+Added option to allow names displayed above other players heads to stay
the same size no matter how far away you are from them.

+Cleaned up LiquidBlock setBounds

-Removed "Quit and play Single Player" button due to launcher now having
"Keep Launcher Open" setting
