Docs website

[willpower232]

@RobThree implied having a github pages site would be a good idea, I think this is the best way of allowing everyone to contribute and maintain documentation.

So there are several hurdles to overcome here, I'll leave my opinions but some more feedback would be appreciated.

where:

• either in @RobThree 's account as a separate repo or under a new TwoFactorAuth-related github organisation so that others could be responsible for merging content updates as necessary
• nothing wrong with a gh-pages branch here but that would require more of @RobThree 's attention to merge content changes

how:

• regular Jekyll (unless @RobThree has another static site preference)
