Hello,

Instead of enjoying the outside world this weekend I have done some development work on OpenGuides.

I now have a pull request that means we can configure OpenGuides via environment variables. This will allow us to run OpenGuides in containers more easily. (I'm also working on that and have a wokring Dockerfile to be PRed later)

https://github.com/OpenGuides/OpenGuides/pull/99

I'm not enitely happy with iterating over all of @variables but iterating over %ENV and extracting what I needed was beyond me.

Comments, fixes and suggestions are welcome on the PR.
