Removes local thumbnails for preview cards.
The --days option specifies how old preview cards have to be before
they are removed. It defaults to 180 days. Since preview cards will
not be re-fetched unless the link is re-posted after 2 weeks from
last time, it is not recommended to delete preview cards within the
last 14 days.
With the --link option, only link-type preview cards will be deleted,
leaving video and photo cards untouched.
