Huge performance boost

I optimized Jumpoline to be 12Mb, so now it's 25% smaller!

There is also a HUGE performance improvement for load times and lag spikes. The black screen at the beginning is now really short (it used to be like a minute long). That's because the background music is no longer loaded into the phone's ram but streamed directly from the file.

I'm so happy I finally fixed this long backscreen!

I hope you'll have a lot of fun with this update :3
