Unicode/string issue on Python 2.7

[cowlinator]

I am running into an issue in artifactory 0.1.17 on python 2.7.14 (32 bit).

The code parsed.append(intern(x)) in pathlib._Flavour.parse_parts() is raising the exception TypeError: intern() argument 1 must be string, not unicode.

I found that this is ultimately due to configparser.ConfigParser.read() in artifactory.read_config() returning unicode strings, but those are never converted via str(s) anywhere.

I was able to workaround this with the following code:

import artifactory
# fix for bug in artifactory module, caused by unicode/str issues
artifactory.read_global_config()
new_config = {}
for section in artifactory.global_config:
    new_config[str(section)] = artifactory.global_config[section]
    artifactory.global_config[section] = None
artifactory.global_config = new_config

Actually, this is a duplicate of #42
