PHP 5.6 preparations

In preparation for the PHP 5.6 release we’ve rebuilt the php-redis and php-imagick PHP modules.
These have already been re-built for existing PHP versions (PHP 5.5 & PHP 7). In addition they are also built for PHP 5.6 now.

Blackfire updates

We’ve also updated our Blackfire probes:
blackfire-agent 1.11.0 -> 1.14.1
blackfire-php 1.16.2 -> 1.17.3
