Make CLI validation commands appear on the web

We dropped the commands when shifting to the new system but agreed it would be nice to have them back. Solves #105.

Just to provide a bit of reasoning behind this solution. I introduced a script validation/certs/utils/cli-validation.py that simply copies the CLI validation data from the individual vconfig.yml files to a single file in the _data folder. When adding new certs, I find it more comfortable to just insert the CLI command into the local vconfig.yml file. If I had to add it directly to the _data folder each time, I would probably forget most of the time :)

Ah, and I see conflicts by merging the lowercase names first. Is it simple to rebase? If not, I could rebase the other way around (though it's not preferred as it messes with the history).
