- The first fix solves the issue that the FooterBar gets stuck somewhere
  in the middle when it is released when not swiping (i.e. without vertical
  velocity).
- The second fix solves the issue that happens when the window is
  resized while the FooterBar is opened.  In that case, the FooterBar
  can also get stuck being partially opened.

(cherry picked from commit 7102c738)

- Fix binding loop
- Use fixed height for sections
- Make the section's image fill all the height

This makes the battery applet show "Elisa is inhibiting..." instead of
"elisa is inhibiting..."

* Make Playlist and Menu buttons more consistent with the others.
* Fix the bug that you can't close the opening menu by clicking on the menu button.
* Add largeSpacing between the volume slider and the shuffle button

This is a re-merge of !232.

Currently the buttons are a bit confusing. This commit clarifies their tooltip text and also
uses the checked state when either of the modes are active.

- Remove the redundant song, album, and artist names from the page, as they
  are always shown elsewhere too
- Use a two-column layout with separated metadata and lyrics when there's room,
  collapsing to a one-column layout with view switcher buttons when there's not
- Add an appropriate placeholder message when no lyrics are available
- Add an option to not show blurred album art background

- Elide/Align stuff properly
- Make the "Show in Folder" action visible again

(cherry picked from commit b2f2e8b9)

Just because we *can* display secondry text, doesn't mean we *will.* So
check for that too. Fixes a common console warning.

Any smaller than about 620, and the player controls become unusable.
