POST request handling and indexing improvements (#636)

* post append improvements:
- parse json primitives for post query
- for text/plain, attempt to parse as json, then as binary
- standardize post append indexing
- include '__wb_method' in urlkey
- add 'requestBody' and 'method' to cdxj
- support unique dupe params for json-to-query conversion

* test fixes:
- update tests for test_inputreq,
- update post-test.cdxj and post-test.cdx

* ci: fixes
- tox: run full test suite!
- disable appveyor

* inputrequest buffering fix:
- never truncate reading POST request, must read entire POST data to avoid hung request in live mode
- truncate final query string to 4096
