More beautiful Water and Beta 19

Just finished adding the caustic effects to the water. That mimics the way light rays reflect off the bottom of ponds and lakes by creating these nice shifting light effects. I also added the ability to reduce the quality of your rendering with Fn+Shift+F2. You can now jump by pressing the space bar. Also, a convenience, you can now bring up the virtual desktop anywhere in the world using the backslash ‘' key. Obligatory screenshots and beta 19:
