Previously, the stack would be reset when switching between screens.
With the new search flow this means that search results are lost, e.g. when switching
from search results to the queue and back.
* implement search for shows/podcasts
* create Playable supertype for queue to contain tracks and episodes
* wip: implement playback of episodes
* load spotify id from uri instead of raw id to fix podcast playback
* show duration for podcast episodes
* implement generic status bar for playables (tracks and episodes)
omit saved indicator for now as the library does not yet support podcasts
* instead of only the last 50 fetch all episodes of a show
* refactor: extract Playable code to separate file
* implement playback/queuing of shows + sharing url
* implement podcast library
* migrate mpris code to Playable supertype
Starting a playlist, album or artist with shuffle enabled always
starts on the first track in it and then plays the rest of the
queue shuffled.
This changes it so unless a track is picked directly, playback
will start on a random track of the selection.
this should significantly reduce CPU usage but is a little bit more complicated.
while we're at it, remove the different screen redraw events and use a combined
event for all screens.
TODO:
the spotify player still needs to update the statusbar at least every second.
this is a pretty big but necessary change and might not be stable yet.
some key points:
- the queue is now responsible for playback controls and track management, as
this was scattered between the queue and spotify objects.
- because the queue is now retained, it should be easier to save it as a
spotify playlist

- move from listview to linearlayout + scrollview
- doesn't redraw the whole view on queue changes anymore
- uses new cursive functions for linearlayout (needs cursive git)
closes#3
this approach needs some (re)work, as the UI is not fully sync'd with the data,
yet. it'd probably be better to have an event system triggered by the queue,
that will cause a UI refresh or similar.
