Larry back

If your hosting customers are lamenting the missing larry skin that cPanel dropped support for, here is how to make it active again.
FYI, Per their changelog, Roundcube did not drop support for larry, they moved it to an independent repository. https://github.com/roundcube/roundcubemail/releases/tag/1.6-beta

Download updated larry zip from:
https://github.com/roundcube/larry/tags

Put the larry files in:
/usr/local/cpanel/base/3rdparty/roundcube/skins/larry/

Edit the config
/usr/local/cpanel/base/3rdparty/roundcube/config/config.inc.php
$config['skins_allowed'] = ['elastic','larry'];

You are welcome.
