Add option to include the full path to file in report

[roscorcoran]

It would be nice to see the option to include the full path in the report, it will allow a single click to view the area of code of interest in dev tools like Intelij.

I can suggest the following change at line 34 (or I can do a pull request if you like?):

      if (el.file !== prevfile) {
        if (options.fullPath) {
          headers[i] = process.cwd() + '/' + el.file + ':' + err.line;
        } else {
          headers[i] = el.file;
        }
      }

See the screenshots below, notice the hyperlink in the full path:
