Adding jOOPL 2.2.0 to the CDN

I'd like to add jOOPL to CDNJS since, being the project's founder and
lead developer I find extremely useful to have the library in a CDN like
yours! Thank you.
The package.json was pointing to "joopl.js" while "joopl.min.js" was the expected file name. Now this is fixed.
