Added music and level editor!

Yes, I uploaded music, lol. It's Synzorasize - Tranquility and I don't have to deal with copyright, lol. No, you can't download the music (right now, anyway) but you can listen to it on SoundCloud. If you don't like it (for some reason since it is calming, xD) or you need everything to be quiet right now you can mute the music in the settings. :D (You can also mute the tab if you are playing in the browser.)

I also created a level editor which is what I was planning to do after I finished twenty levels. You can add and move stuff around (you can't delete anything yet, though) and play it! You can hold shift to be more precise in the editor and left and right to move the editor around. You can even trigger the camera. There are no teleporters or switches yet (those would be very hard to implement right now, xD, and as for switches I would have to change the current system, lol) but you still have the basics! :D The color buttons on the left panel can change the color of the thing you want to place. Of course, the Orb, Hazard and Player buttons are disabled on the white option because white orbs and white players would make no sense, xD. And I have an alternative for white hazards (see Level 4). (Also, the Player button changes the color of the player.)

The editor might have some glitches and bugs, though, lol. I will also try to improve the game more and more as we go along. Hopefully, you like it! :D
