Lix 0.10.9

Replace Lix's water with better-looking water. We have:

• My old water. It's 48x48 in several colors, it's in 3 colors only, and it's crudely wavering back and forth. Doesn't look too harmonious.
• Matt's water. This is the abstract-looking sawtooth water that is completely unanimated except for its sideways scrolling.

Amanda's tar looks good, we can keep that.
