bug: README options 'remove' is not functioning as described

[jf3096]

I have reviewed the source code and find out that in CLI mode, remove is treated as only. Howerver, in programing mode which I "require('gh-pages')" the following code wont work as source code "config.remove" has never been used.

ghpages.publish('dist', {
  remove: "*.json"
}, callback);
