NimbleClip 1.13.1

• A paused YouTube audio download stays paused when the app is closed and
  opened again, and keeps what had arrived. It used to carry on by itself at
  the next launch. Its card also shows how much is kept, where it read 0 B.
• On Android 7.0, YouTube qualities above 360p are no longer offered. That
  system cannot join their picture and sound, so such a download fetched
  everything and then failed. 360p and audio download as before; Android 7.1
  and later are unchanged.
