Add script to deploy to greenqloud instead of github

We need some green cloud credentials which can share, (which I'll put in the keepassx file, but I've used this script to deploy a version of our site to http://gq.cleanweb.org.uk).

James, or Jason - would you skim this code to see if it's intelligible, to merge in?

Then, I'd like to try deploying to magma powered servers this weekend, using this approch instead of teh githubs.
