Console scripts compatible Linux/Windows

[tantale]

Instead of using scripts for artifact and repo commands, on can use console_script.

> tree /F Scripts
SCRIPTS
    artifact-script.py
    artifact.exe
    artifact.exe.manifest
    [...]
    repo-script.py
    repo.exe
    repo.exe.manifest
    [...]

This works perfectly on Windows:

> artifact --help
usage: artifact-script.py [-h] [-D]
                          {upload,delete,get-metadata,set-metadata,resolve}
                          ...

A command line tool for working with artifacts

positional arguments:
  {upload,delete,get-metadata,set-metadata,resolve}
    upload              Uploads an artifact to repository, can detect name and
                        version from filename
    delete              Deletes an artifact from repository
    get-metadata        Prints artifact's metadata
    set-metadata        Sets artifact's metadata
    resolve             Resolves artifacts' URLs

optional arguments:
  -h, --help            show this help message and exit
  -D, --debug           Print lots of debugging information

I all fix minor problems in setup.py.

Awesome work! And the first pull request :) I relly do appreciate it. Once merged, you'll be always recognized as the first contributor to this project 👍

To be honest, I have never tested it on Windows, so I'm glad that someone did it.

Regarding the content: it looks like lot of improvements. Unfortunately tests for py33 and py34 are were failing after your change. I am was not sure, which of that 10 commits broke the tests.

It is easy to enable travis in your fork, so you'll see the build results for each of your commits.

You fixed the py3x builds faster than I finished this comment! 👍 Amazing work!

Gonna merge it :) Regarding releasing a new version, I will release it immediately after fixing #16, which I expect to happen in less than a week.
