Update to support new wordpress zip format

Hello,

I noticed that since Wordpress 4.0 came out, the `getwordpress` command no longer works properly with the latest Wordpress zip file. I have updated the script to use the `download` module  in place of the `hyperquest` and `adm-zip` modules. In addition I added the `download-status` module to all for showing the progress of the download.

`console.log` does already make a `\n`, so you should not add it.
