Title: lib/detector.js not properly normalizing pathname in Windows.

Hey Vesln,

We were having trouble with temporary on a windows machine that had
```javascript
process.env.TEMP = process.env.TMP = 'C:/path/to/some/user/appdata/local/temp';
```
The detector fails to properly resolve this path (by adding a needed trailing slash) such that temporary was creating folders:
../../appdata/local/temp134545353453.5453 etc.

It is not guaranteed that windows dir paths will end in '\'. It should also be noted that adding additional '/' to a windows path is okay because windows will correctly resolve the path anyway see stack overflow here:

http://stackoverflow.com/questions/4158597/extra-slashes-in-path-variable-of-file-copy-or-directory-createdirectory-met

Made the fix in detector.js with comments as well as some unit tests related.

Please accept pull request.

Thanks.
