Show who changed which line (`git annotate` output) via UI

[mbunkus]

I'm using the gitbackend plugin for the improved history tracking. I often find myself trying to figure out who changed a specific line in a page, which is very tedious to do with DokuWiki's own history page diff feature, but is incredibly easy with git annotate /path/to/file. At the moment I have to drop into a shell to do this with the gitbackend plugin, and I have to have privileges to access the raw files in the file system to do so.

It would be nice if there was a feature in DokuWiki itself that showed the output of git annotate for the currently visited page. That way all users could use the functionality, and I wouldn't have to drop into a shell & navigate through the file system for most trivial cases.

Thanks for considering.

This feature request makes much more sense if #63 is implemented, too.
