A couple of cleanup changes
Adding initial jsonlint support
Adjusted the line reported reported by jsonlint so that it's what the lint reporting engine expects
Removed extra quotes around received value and added period at the end of the error from jsonlint
Modified the sample json files to generate errors so they can be reported by jsonlint
Merge pull request #71 from MiguelCastillo/miguel/jsonlint-support

Implement JSON linting
