Temporarily fixing #24 for linux/unix users

[jzbor]

This PR add support for two config files: ~/.config/nameinator/nameserver-globals.csv and ~/.config/nameinator/domains.txt. Note that they are overwritten if their counterparts exist in the current working directory. So this really just quick fixes #24 without changing the originally intended behavior otherwise.

Thanks man - I will actually check if the changes will work for any OS - linux, win, macos - so we will have no issues. Hope to be through that on weekend :)

Any updates?
