pull to refresh, hide the bar while searching, animate the progress inset, circular warm damping

- replace the library sync button with pull-to-refresh on every tab
- hide the tab bar while searching so only the search field sits above the keyboard
- animate the mini player progress bar between full bleed and 8dp inset rounded ends as the tab bar comes and goes
- make the warm-hue saturation damping continuous across the 0/360 hue wrap
