Make the icon fit Android guidelines better

[hawkrives]

Probably the easiest way to do this is to make an Adaptive icon, with a white background and the penguin. At least that way the corners will be rounded.

I'm thinking I could do a white silhouette of the penguin, on a dark blue background with the angled Material shadow. I think that's be nice.

Are you unhappy with the current adaptive icon redo?

[hawkrives]

It's visually complex for an Android icon.

Also it's not actually an adaptive icon. I gave up on that in favor of just making the icon work, so it's still just PNGs.
