• Fix timestamp default value for good this time.

• fixes database initialisations for MySQL

Small maintenance release. ChangeLog:

• Add option to disable PHP version check.
• Downgrade required PHP version to 5.6.18.

This is release 2.0.0 of RCMCardDAV!

I have delayed this release way too long, so I just tagged the latest commit after checking that it works with Roundcube 1.2.2.
Please follow the INSTALL file when installing RCMCardDAV and remember that there is NO UPGRADE PATH from RCMCardDAV 1.0.0!

Enjoy!
