Add OAuth support; update README

[andrewalexander]

I hadn't pulled in your last 10 commits, but I wanted you to see this PR so you know what I am talking about (a la Linus Torvalds' quote: "Talk is cheap. Show me the code").

I haven't tested that last commit - I didn't realize the PIL module actually got added in. When I originally forked it, the PIL module was imported, but not used anywhere. I see you added that create_spritesheet() function and it uses that library there. It was really only a few lines, so I am fairly confident it will work; the important piece was the authenticate.py (imo)

I was contemplating adding a Flask microserver that spins up, handles that initial auth, and then spins down. Pretty much like the example on the PRAW docs.

PIL has always been used for creating the spritesheet, but that's not super important.

I had a look at the reddit oauth docs on sunday and decided to postpone working on the oauth implementation myself untill next weekend - i'm wondering why it would be necessary to run flask in the first place? Surely the requests module would suffice, or is there something about getting the oauth tokens i'm not aware of yet? (I still need to get a better understanding of the oauth setup for a script like this)

[andrewalexander]

Short answer is you don't - This manual process works just fine because the web browser redirects to the response_url that was passed as part of the initial handshake process. I am not sure of a way around manually clicking allow in the browser.

I can type up a longer answer, but I think the README and the linked URLs would do a better job than I at explaining the process.

Cool, i'll merge this PR with a develop branch for now until password auth is no longer working, or when we can figure out an automated way to get the tokens.

Have you seen into any praw extensions to handle the oauth login? I saw a couple on sunday but none that look particularly stable.

Merged into oauth-dev on the main repository for now, when we get oauth working as automated as we possibly can (hopefully it'll require no user input), i'll merge into master.

Did you use pip or homebrew to install PIL?

[Andygmb]

It actually uses Pillow, a fork of PIL, my bad.

pip install Pillow should sort it out - This is why I should really sort out the installation section a bit better, and perhaps check for those modules in the setup.py. #20
