Web pages in separate repo

[xoft]

I have successfully tried this on the cuberite.org domain, it is currently hosted in the cuberite.github.io repo (the repo name is somewhat arbitrary, it just needs the .github.io suffix)

So I propose we move the main webpage away from the C++ source code repo.

I was wondering, with the old wiki we had a problem with the pages being crippled by spambots. How about if we created a separate repo for wiki.mc-server.org and do wiki-like pages in there, information-wise, but the changes would go through the normal GitHub process of pull requests? It will probably be a bit more involved to make changes, but we'd get rid of the spambots.
