Title:
  Image provider blocking the UI thread

Status in Thumbnail generator for all kinds of files:
  Fix Released
Status in thumbnailer package in Ubuntu:
  Fix Released

Bug description:
  Steps:
  * add some music to your device (phone or desktop is fine)
  * [on desktop] install unity8 and run "unity8-dash -mousetouch"
  * bottom-swipe to the Manage screen
  * select the "My Music" scope
  * scroll quickly

  Expected:
  * scope scrolls smoothly, even if there's no images

  Current:
  * scope scrolling blocked for seconds at a time

  This seems to be most visible the first time, when images are not
  cached on disk yet.

  AFAIK the impact of this is elevated by the fact that Qt serializes
  requests to image providers, so when it's blocked to download one
  image, it will not continue to the next image etc.
