[author] Merge file to Profit Button repository without change the version

Please merge these changes without changing the current version number (1.0.0) of [probtn repository](https://github.com/cdnjs/cdnjs/tree/master/ajax/libs/probtn/1.0.0)

We have removed protocol-specific links  in external libraries (http:// and https:// to just //) and added a few more files to decrease server load. These changes are backward-compatible, so we'd like to leave version number intact.

Thanks!
