Improve Doc versus Rules list inside _config.sh

[Silicoman]

Hi,

We actually have a list rules to add eco-design tag.
RULES_KEYS=css:S4655,php:S2014,Web:ItemTagNotWithinContainerTagCheck
It will interesting to improve documentation about this list.
I was thinking about to making a markdown about this rules and parsing this markdown to got keys.

Hi @Silicoman,
very good idea.

Actually, rules list in _config.sh file are only here for my tests.
For me, we have to do an audit of our existing rules and check if they are already present natively in SonarQube : check issue green-code-initiative/ecoCode#34

But I'm agree with you, if we can improve this system, no problem.

Thank you, sir !

PS : please think about install process for developers
PS2 : Warning, because there is a PR created during hackathon #18
