Add POD-hint: REMOTE_ADDR is not set when using proxy via filesocket
Add include function to config files

The Perl config files now can use "include" to include other config
files. Example:

    # conf/config.pl
    {
        database => include('conf/database.pl')
    }

    # conf/database.pl
    {
        host => ...
    }
