jsonlint doesn't need to be installed globally

[notslang]

From the readme:

Before using this plugin, you must ensure that jsonlint is installed on your system.

Actually, jsonlint will be installed automatically with this package, and all you need to do to use that copy of jsonlint is clear out the "Jsonlint Executable Path" setting so the default takes effect... And that is much easier than trying to get the globally installed one to work.
