If the option is enabled, it will try to find a meta tag containing
the page description and keywords, just like we do for the page title.
It will either look for regular meta tag or OpenGraph ones.
The option is disabled by default.
Note that keywords meta tags is mostly not used.
In `configure` template, the variable associated with this setting
is `$retrieve_description`.
Fixes#1302
- add a default thumb size value (125x90px)
- improve private vertical bar visual, especially with thumbnails
- translations
- add a sync thumbs button in tool and empty picwall page
- fixes WT download mode in JSON config
This feature is pretty much useless these days as browsers have builtin features to support the thag "<meta name='referrer'", so keep the setting page as clean as possible.
Also, avoid advertising it too much, because I'm pretty sure it doesn't work very well with markdown descriptions (as Parsedown have some trouble regarding URL detection (without MarkDown link tag)).
