10849	improve TMS imagery caching	bastiK	team	"Currently, the TMS caching is a little strange:

(1)

* After first download, the offline cache will be used for 7 days.
* From that point on, the check period is reduced to 1 day.

A check is as good as a download, so instead it should only check after another 7 days, and so on.

(2)

* When cache is stale, and image cannot be downloaded (e.g. no network connection), it displays no tile.

Instead, the old cached image should be used. This is better than displaying nothing."	enhancement	closed	normal	15.03	JMapViewer		fixed
