This commit contains the entire btcjson repository along with several
changes needed to move all of the files into the btcjson directory in
order to prepare it for merging. This does NOT update btcd or any of the
other packages to use the new location as that will be done separately.
- All import paths in the old btcjson test files have been changed to the
new location
- The coveralls badge has been removed since it unfortunately doesn't
support coverage of sub-packages
This is ongoing work toward #214.
Since the github contributors list only lasts for a period of time, it's
better to also maintain a contributors list in the repository rather than
solely relying on github.
