Fractal World

-Added Custom Fractal Generation!!! Type in an equation, get a fractal picture as a result!

-Fixed a few bugs with the config file

-Made it slightly faster

-Added a new Column Clearer for Parkour grid, in a reference to parkour civilization

-Removed chunk randomizer, because it was causing problems. I will add it back in the future in a better way.

-Created an entire new math language for the Custom fractals. Check out the wiki to see how to use it!
