Updated when version
Exposed a commandOptions so that it could be overridden might be useful
upon passing a proxy or other settings and added a
stop-phantomjs.js file to kill the phantomjs.exe in win32. Updated the
readme.md
Reverted back the "when" version

Reverted back the when version, changed by mistake
Merge pull request #5 from daxsorbito/master
