[Redesign beta] Clearer lyrics navigation

[AverageHelper]

Currently (Android beta 0.9.12), tapping the Lyrics button in the Player screen appears to navigate to an entirely new Player screen, whose only differences are that the Queue button and gesture are removed, and album art is replaced with a lyrics scroll. If no lyrics are available, the button still behaves the same, only instead of a text scroll with lyrics, a notice is placed beneath the album art.

I wonder if it might be more intuitive to have the Lyrics button instead toggle the album art into the same lyrics scroll (perhaps inverting the button's colors with its background or something, to show selection), instead of the current sliding-page-replace animation. (This might make the swipe-on-track-title gesture not make much sense anymore, so maybe a tap instead would work? Or maybe remove that gesture entirely, in favor of a new item in the hamburger menu list to toggle the Lyrics mode.)
