Fixes, tweaks and visual improvements

Went ahead and decided to do what you had in mind and made Playing Bar expand to fullscreen. Here's what I did:

• Assigned EventListener to 'Root__now-playing-bar' instead of 'expand-playing-bar', because 'expand-playing-bar' is hidden when the Playing Bar is expanded, so we couldn't register clicks in expanded mode to minimize it;
• Made sure that we click the extra div expandPlayingBar creates over compactPlayingBar so that Play button doesn't trigger expansion, as before;
• Once we're fullscreen, it's possible to click the entire part above the controls to minimize it back to compactPlayingBar. This way controls themselves don't trigger minimization, and clicking the album art minimizes the Playing Bar in any case; this addresses https://github.com/janch32/SpotifyWebWrapper/issues/8;
• ReactToURLChange needed two extra parameters to restore NavBar copied from the PlayingBar function for cases when we click links when the Playing Bar is expanded.

What do you think?

Awesome, that's exactly what I had in mind!

By the way the reason why the app is not yet updated on the store is because I'm in the process of completely rewriting styles from one big messy CSS file to multiple organized files in SASS (it's almost done).

I also changed few things - for ex. I moved the user button from navbar to "your library" page to solve the navbar overflow issue once and for all. I also found out, that Spotify has hidden second media controls in .Root__media element so now the app will use this hidden media control in fullscreen.

Here's the "new" UI in action (it's not yet finished so you can still see few elements that are out of place - like the connect button in fullscreen playback). You can also see that now the fullscreen transition can be animated.

Ooh, that's quite the overhaul you've been doing. The animations look sweet, and that's an elegant solution with the User button, cool stuff!
