Level Editor Finalized

You can now make Levels! Load up GameLevelMaker. It's a god awful god
class, but it works. It should be pretty self explanatory, but there's
some cool stuff in there. You can place a player, add every kind of item
(I left out PlayerWarper - I'm not sure how we're going to do that one).
Most importantly, you can also Edit the Pillars! Click edit pillars on
the right after GameLevelMaker loads up and click on the mock-screen,
and they should switch on and off!

The coolest feature I think is the Randomize Pillars feature. It makes
(mostly) complete levels. It might be too densely populated still, I
didn't spend much time tweaking the coefficients, but It does a good
portion of the work for you! Have fun making levels :satisfied:

There's a bunch of other small changes I've made, mostly fleshing stuff
out. If you have any questions about what I did, let me know :)
