Add site-map and possibly more

[eXpl0it3r]

The help search engines we should add a site-map and possibly do more optimizations, especially regarding "deprecation" of tutorial/documentation URLs, e.g. 2.0 vs 2.3.2.

For outdated versions, we could use a redirection banner like Boost does.

Concerning 2.3.2 documentation, see my comment here.

[eXpl0it3r]

That doesn't solve the indexing issue, which this issue has been created for.

What issue?

For outdated versions, we could use a redirection banner like Boost does.

Too bad I can't remember why I removed them. I'm sure there was a reason.

[eXpl0it3r]

Google preferring old documentation version over newer ones.

[LaurentGomila]

Ah, ok. And would a site-map solve this problem efficiently? (this is a real question, I'm not arguing)

[eXpl0it3r]

I'm not sure, that's why I wrote "possibly". It's something I'll have to investigate and only wanted to make a note so I don't forget it.

Mostly fixed with #111
Sitemap might still be a good idea.
