fixed httparty dependency
removed tabs, used ruby 2 space indention
require_relative because the lib is not found without it
testing against live data. there are new votes on the live system :wink:
added vcr to test against recorded data, fixes #3

Now it replays the tests against recorded data instead of live data. That
way the tests stay more stable. E.g. the number of votes changed in the last
few months and the tests failed because of that.
Merge pull request #4 from bitboxer/repair-tests

Don't test against live data, use vcr instead
