This commit also adds a new command, docshelper, with some utility funcs that adds a JSON datafiles to /docs/data that would be a pain to create and maintain by hand.
Fixes#3242
We should get some new ones in there.
Also shuffle the order. This also means no merging into 0.15-docs ...
Which also means we should get a release out there ... soon!
See #2055
Also See https://github.com/BurntSushi/toml/issues/129 for an explanation to the little bit ugly dates.
