Allow setting PAD_API_KEY from command-line or env? #8

Then we can override b384354e95/config.py (L6) without having to edit the file? It might also be nice to create an error check if the key is not set & error out with an explanatory message?

I did:

diff --git a/config.py b/config.py
index eca98cd..d63c027 100644

 class Config(object):
        APPLICATION_ROOT = '/'
        PORTNUMBER = 5001
        PAD_URL = 'https://pad.vvvvvvaria.org/' # with a slash in the end!
        PAD_API_URL = 'https://pad.vvvvvvaria.org/api/1.2.15/'
-       PAD_API_KEY = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
+       PAD_API_KEY = os.environ.get('OCTOMODE_PAD_API_KEY', '')

And then:

export OCTOMODE_PAD_API_KEY=...; make run
