Title:
  Add offline cache

Status in “qtlocation-opensource-src” package in Ubuntu:
  In Progress

Bug description:
  The app should be able to cache downloaded tiles to be used in future
  runs of the app.

  In contrast to the download tile pack feature, that allows downloading
  a region before going on holiday; this would provide faster viewing of
  previously viewed areas especially when the user has poor signal, as
  well as less bandwidth usage etc.

  At present, the QML component caches downloaded tiles while the app is
  running, but upon closing the app this is all forgotten, and it must
  download from scratch again the next time it is loaded. So, tiles
  should be stored in a permanent cache, so that it is not required to
  download them everytime the app is started.

  Note: Similar apps allow the user to specify the size of the cache, to
  meet their requirements. So, they can set the cache size to 1MB or
  500MB etc. depending on their needs.
