Webmail: Compress static resources.
We leave dynamic pages (those passed to PHP-FPM) alone for now: compressing them would make us vulnerable to BREACH attacks. This will be revisited once Roundcube 1.5 is released: 1.5 adds support for the same-site cookie attribute which once set to 'Strict' makes it immune to BREACH attacks: https://github.com/roundcube/roundcubemail/pull/6772 https://www.sjoerdlangkemper.nl/2016/11/07/current-state-of-breach-attack/#same-site-cookies
