Title:
  Cache preview and thumbnail images

Status in Ubuntu UI Toolkit:
  Invalid
Status in The Unity 8 shell:
  Fix Released
Status in “unity8” package in Ubuntu:
  Fix Released

Bug description:
  Currently the Dash always reloads preview images. This includes both
  web results such as those from Amazon or local files such as images.
  It should cache those to reduce networks and battery usage. It should
  follow appropriate standards such as the freedesktop.org thumbnailing
  standard or the Media Art storage standard.

  There should be only one centralised location where thumbnails are
  fetched and stored and that should be in the dash. This is because we
  want to do load images lazily, and the dash is the one piece that
  shows images to the user.

  An example data flow would go like this:

  - mediascanner scans the user's music files
  - it looks up album art download addresses from last.fm
  - it stores the address somewhere
  - user types a music query
  - the music scope returns results whose metadata list the download address
  - dash loads the actual images as necessary and stores them in the cache
