Replace the colon in environment variables with underscore

[suda]

I noticed that DigitalOcean doesn't like the colons in the env variable names:

Would it be possible to replace them with underscores to look like TWITTER_CONSUMER_KEY?

Hi! This is something handled directly by the framework I use, but the good news is that you can replace the colon : separator with the double underscore __ one (cf the documentation if you need more insights).
