Ok, so installing greg from git using pip install --user git+https://github.com/manolomartinez/greg.git doesn't create the following directory:

/home/nick/.local/lib/python3.4/site-packages/greg/data/greg.conf

Which means there is there is no global greg.conf

If greg.conf is missing then greg doesn't know where to find the default data directory which in this case is '/home/nick/.local/share/greg/data`

So this commit bf15fd3 fixes the fallback to this location. Let me know if this is a good way to handle this or not.

Ugh, yes, thanks for opening this issue, Nick.

The right way to do it, I think, is to get setuptools to install package data as we intended. This is a famous mess, but I think I got it working now.

This commit accomplishes it, I think.

Works perfect! Thanks.
