ISP 3.1 Debian Testing compatibility
I noticed that ISP 3.1 chooses debian40.conf.php in case of debian testing and other unknown debian versions. That file specifies PHP5 and therefore installing ISP 3.1 on fresh debian testing with PHP7 results in half-broken installation (nginx throwing 502 bad gateway error because there is no PHP5 socket specified by ISP vhost).
Maybe it should be wise to change the default behaviour to assuming debian testing/sid in case of unknown versions, and include PHP7 in that configuration file - it should be pretty much the same config which ubuntu 16.04 uses, just with different name.
Thanks.
