Cannot start after a clean install with a simple configuration file

Hi there,

I ran into this issue today after pip install slack_machine and follow the tutorials.

My local_settings.py is

SLACK_API_TOKEN="hidden"
PLUGINS = []

Then I ran slack-machine and saw the output below:

Initializing Slack Machine:
    Loading settings...
    Initializing storage using backend: machine.storage.backends.memory.MemoryStorage
    Loading plugins...

Starting Slack Machine:
    ✓ Connected to Slack
    ✓ Scheduler started
Bottle v0.13-dev server starting up (using WSGIRefServer())...
    ✓ Web server started
Listening on http://0.0.0.0:8080/
    ✓ Dispatcher started
Hit Ctrl-C to quit.

ValueError: Only http proxies are supported

The server is an Amazon Cloud server, no proxy is set (env | grep -i proxy is empty).

What's interesting is that, if I run this locally, and install a HTTP proxy server and set it in the config like

HTTP_PROXY="http://127.0.0.1:1087"
SLACK_API_TOKEN='hidde'
PLUGINS=[]

...works like a charm.

I may have misunderstood but how to properly run it on the server without any proxy? Thanks!

Confirmed this is a package version error. Try pip install -r requirement.txt after a clear virtualenv setup fixed the issue.
