Extension documentation not in sync with code

[rchl]

In https://github.com/jensl/critic/blob/master/src/tutorials/extensions-api.txt#L153 these APIs are listed:

|   Changeset getChangeset(string a, string b);
|   Changeset getChangeset(Commit a, Commit b);

But they don't seem to be implemented as far as I can see in https://github.com/jensl/critic/blob/master/src/library/js/v8/critic-git.js#L692

A bit of a shame because I wanted to use it. :)

Ah, I can just pass an object with parent and child properties and it will do what I want. So the issue is in documentation being wrong only.
