Make ATOM toolbar button optional
 * ATOM button display is now configurable using the SHOW_ATOM variable in index.php or data/options.php (defaults to false)
 * Fixes https://github.com/shaarli/Shaarli/issues/24
thumbnails: force HTTPS for youtube, imgur, vimeo
 * other services also provide thumbs over HTTPS, but the rewrite expression is more complex, so left out for now
