- jsondiff has a bug/feature: if you compare not empty json object with
  empty json object it will show no difference. Comparing empty with not
  empty will show difference
- jsondiff its not actively maintained (last commit 11 months ago)

- Response validator can now ignore specified fields in
  json response when comparing with patters
- Example in get_profile in bridge_api

- rebranding
- accepted different future cashout_time (prior to HF17 it was taken from root and we don't want to introduce hardfork differences to HiveMind)
- accepted different post_id
- accepted lack of double-escaped slashes in json_metadata (now is better)
- corrected indent for tavern's 2 spaces
- corrected cases of CLRF
Comparison script now removes .diff.json and .out.json files from previous run
Comparison script now generates .out.json with error message in case of error/no response (all failing tests have .out.json file)
Added comments to failing tests why they are failing
Added comments to tests with empty results why there is no other option

- Added pattern validator
- Added patterns for 5000000 blocks
- Added bridge_api pattern tests - failing tests are marked with XFAIL
- Added marks to all tests

- Response validator has been added: it validates if error or result
  fields are present in response. Occurence of error field will fail
  the given test.
- In order for validator to work a path to test directory must be added
  to PYTHONPATH i.e you can run py.test from inside of tavern dir using:
  PYTHONPATH=$PYTHONPATH:$(pwd) py.test -v
