Fix vidscraper to work with requests >= 1.0

[willkg]

This fixes all the json -> json() calls. Everything in the test suite passes, so I think it's good to go.

The test requirements file needs to be updated. The travis run is failing because it's still installing requests < 1.0.

[willkg]

What version do you want to peg it to?

[melinath]

Latest is fine with me. 1.2.3?

[melinath]

Maybe also remove the commented-out line from setup.py, as long as you're doing another commit anyway?

[willkg]

^^^ Nixed the commented out line and updated test_requirements.txt.

I'm also concerned that there might be some issues with OAuth handling. I seem to remember that being an issue last time I looked into doing this transition... and the OAuth sections aren't currently covered by the tests. :-p Did you happen to look into that? If not, I'd probably be fine with merging this as-is anyway, and just fixing those issues when they come up.

[willkg]

I didn't look into that and don't use the Vimeo support, so it's not something I'm set up to look into very well.

[melinath]

Kk, no worries. Looks good.

Thank you!
