Update requirements.txt

[HarinderToor]

oauthlib has been upgraded quite recently, and it is causing errors with Twython because of oauthlib. I have fixed the issue by downgrading to oauthlib 0.6.3 locally.

Here are the recent changes of oauthlib: https://github.com/idan/oauthlib/commits/master

If this is breaking Twython, why doesn't twython simply pin the version of oauthlib? It can without any issue do so, while allow requests-oauthlib to continue supporting 0.6.2 and beyond.

Coverage remained the same when pulling 3658a1e on HarinderToor:master into 23fc41b on requests:master.

That's a good idea. However, I just thought this might be breaking other modules as its version was bumped recently and this pulls the newer versions.

@HarinderToor sorry I broke Twython :( Will add it to my list of dependent projects to check before releasing and ping you as per http://oauthlib.readthedocs.org/en/latest/release_process.html

I did a quick test and it seems that only the removal of oauthlib.common.log was the issue. I added that back in and did a quick release of oauthlib. Please confirm whether that helped!

@ib-lundgren I am sorry, but that was ridiculously fast. Thank you, that fixed the issue!

Edit: Is it worth changing the requirements to something more static to prevent this type of problem in the future? I can't be the only one.

@HarinderToor no problem. I managed to release 0.7.1 while tagging it 0.7.3 on Github. Ah the joys of jet lag.
