Version 0.0.1.7 - Musical Note Animations, and minor fixes

Made some floating 8th note animations in Aseprite to put over the radio and keyboard while they're active.

Also fixed a rather large mistake: in the prior version I forgot to set the flag for the coffee state back to the normal starting value. I had changed it to enable faster testing of the Coffee + Radio interaction, but I forgot to change it back apparently? Or maybe I just did that after exporting it.. either way, the coffee maker now progresses through its states as intended.

Still may add some other features, like other waveforms for the synthesizer/keyboard -- this is a common and important feature in most synthesizers and adding it would be relatively simple so I think it should be included. Some kind of filter frequency (aka cutoff) control would also be interesting, though implementing that is a bit trickier because it would normally use a slider.

Also I may still add more audio tracks, though I think the four currently in it make a very nice and neat package, fits the retro/low tech vibe that low poly stuff fits into in the broader sense.
