Safe directory creation

[patrickhousley]

Library is throwing an error when one or more of the parent directories of the path passed to reportDir does not exist.

Gulp task call:

gulp.task('test:execute', mochaTest({
  sources: paths.mochaTests,
  mochaOptions: {
    reporter: 'mochawesome',
    reporterOptions: {
      reportDir: paths.mochaReport,
      reportTitle: 'Core Build',
      inlineAssets: true
    }
  }
}));

Gulp task source:

export const mochaTest = (options = {}) => {
  let {
    sources = [],
    mochaOptions = {}
  } = options;

  return () => gulp.src(sources).pipe(mocha(mochaOptions));
}

When using a custom directory for the report, mochawesome currently expects to only create one new directory. I'll see about modifying it so you can create multiple dirs if they don't exist.
