Upgraded Roundcube Webmail from 1.3.0 to 1.3.1.

We just published the first service release to update the stable version 1.3 which is the result of some touching-up on the new features introduced with the 1.3.0 release. For example it brings back the double-click behavior to open messages which was reduced to the list-only view. Or because the switch to change the mail view layout was a bit hidden, we also added it to the preferences section.

The update also includes fixes to reported bugs and one potential XSS vulnerability as well as optimizations to smoothly run on the latest version of PHP.
