custom rmdirp for 'Windows.old' folder

delete-windows-old.js

/**
 * Short script (**Note** needs to run with `--harmony` flag (testing on node 0.12.0))
 * for getting rid of the 'Windows.old' folder and also is a custom rmdirp of sorts: overcomes the memory limitations of the rmdirp module when running on windows (and maybe linux?).
 * Just replace `pathToOperateOn` with the location of your 'Windows.old' folder.
 * Run it and celebrate!  :-D (thumbsup)!  
 * (Also excuse the big tabs/spaces.  Had some issues with my pc, had no software installed and use notepad to write it lol!)
