[Jonathan Bedard]

We should have a `git-webkit log` and `git-webkit blame` command that use identifiers in those commands and their output.

This is almost identical to Blame.
The only differences are line 42 and Line 70, which can be changed to
```
sys.stderr.write("Cannot run '{}' on remote repository\n".format(cls.name))

return FilteredCommand.main(args, repository, command=cls.name, **kwargs)
```

Is It intentional to use 'Blame.pager' rather than 'cls.pager' ?

Ditto.
