Updated the composer.lock to install satooshi/php-coveralls

Add .coveralls.yml to stop errors.

Added coverage_clover pointing to correct location.

json_path now... anything to get bin/vendor/coveralls to actually execute!

Only push coverage reports for a single version of PHP

Add whitelist + exclusion files to coverage.

Reduce code coverage % by processing all files :-)

Beware adding additional directories for tests without setting up config + mocking the rest of the environment.

Don't show uncovered files.

Attempt upload for all PHP versions. Is this stacktrace always generated?

Return to "true" for uncovered files.

There is a path problem somewhere!
