hash symbols in config.cfg causing an error

[pb66]

ref https://community.openenergymonitor.org/t/permanent-raspberry-pi-booting-after-failed-emonpi-update/10963/22?u=pb66 and https://www.php.net/manual/en/function.parse-ini-file.php

Originally I submitted PR #37 to swap out the hashes for semi-colons but that caused and issue for the bash script so I closed it again.

Note that reading the parse_ini_file() changelog the use of hashes should effect php7.0 users, but as it turns out, the linked case is a php5.6 setup ????

I've implemented a fix for this that filters out all lines that start with a #:
