Allow for multiple palette files rather than hard coding to flam3-palettes.xml.

Make xaos display a matrix rather than a single column. This will be moved out into its own tab since it's no longer xform dependent, but that will be in a future commit.

Remove xaos from/to button since it's no longer applicable.

Add test function to Isaac to return just one random byte. Might be used in the future.
