Proposal to restructure repo

[peterdesmet]

@tucotuco @pzermoglio. I discussed this morning with @baskaufs if the Quick Reference Guide should be part of the standard. If it is, it needs to comply with how human documentation, section "3.2.3 Layout and style". We think it should be the first brick of a community-maintained Darwin Core website (where we have more freedom) and not part of the standard.

So, we here propose a new structure for the repo:

1. All content considered part the standard is in directory standard. Generic enough if you used for other vocabs
2. The standard contains (as by the guide) vocabularies and documents
3. Vocabularies contains only one: term_versions.csv
4. Documents contains the 4 guides: this will have to comply with how human readable documentation should look like, but that is something that we can do (and almost the case)
5. The quick reference guide is part of a /www directory, in the directory guides. The www directory can be seen as the start of the community-maintained Darwin Core website, which in the future might not even be part of this repo.

That sounds good to me. More freedom!
