Build error with Sphinx-1.8.1

[scudette]

This currently fails with

$ tinker --build
Running Sphinx v1.8.1

Extension error:
Config value 'author' already present

The problem goes away by remove the line

app.add_config_value("author", "Winston Smith", True)

in https://github.com/vladris/tinkerer/blob/master/tinkerer/ext/blog.py#L126

The problem of course is that pip install tinkerer is currently broken because it does not pin the version of Sphinx to its tested version.

The reason for this is that author is now a built-in configuration variable in Sphinx. See sphinx-doc/sphinx#4518.

I would suggest renaming tinkerer's author variable to another name, or re-using the variable provided by Sphinx.

This is not fixed.
