Roundcube Webmail 1.2-rc

This is the feature-complete version for the next major version 1.2 of Roundcube webmail for final testing. After adding PHP7 support and PGP encryption in 1.2-beta, this release candidate finalizes that work and also fixes two security issues.

IMPORTANT: with this version, we finally deprecate some old Roundcube library functions.
Please test your plugins thoroughly and look for deprecation warnings in the logs.

Also, with the upcoming stable release of 1.2.0 the old 1.0.x and the 1.1.x series will only receive important security fixes.

Please note that this is a release candidate and we recommend to test it on a separate environment. And don't forget to backup your data before installing it.
