delete cached icons that have not been accessed in over a year

Browse Source 
The icon files are downloaded for each version of the app.  Over time, old
versions will pile up.  This cleans out the ones that have not been used in
over a year.

On < android-21, this will delete icons that were downloaded over a year
ago even if they are still in use because it is only possible to check
mtime, not atime.
