* Problem: Source files contain no license info
Solution: Add comments with SPDX license info to source files
* Python 3 files don't need # -*- coding: utf-8 -*-
- Created three new JSON Schema files for the v2.0 transaction schema, based on the v1.0 files. The only change is the allowed value of version (from "^1\\.0$" to "^2\\.0$").
- I didn't delete the v1.0 JSON Schema files because we might want those some day (to validate old transactions).
- Updated the __init__.py in the directory with the JSON Schema files so that it now uses the version 2.0 JSON Schema files.
- Updated all relevant tests. I only found one, in tests/validation/test_transaction_structure.py
- Updated VERSION in common/transaction.py
- Checked to make sure the example HTTP API docs show "version" with value "2.0". They do.
- Updated the docs page about "The Transaction Model". It just points to the IPDB Transaction Spec.
- If someone submits a transaction with "version" having value "1.0" then the error message comes from the JSON Schema checker.
