Title: send not works on Windows

koa-send throws "malicious path" error on Windows.

Because `path.normalize` converts a drive name to lower case (ex. `C:\hello.txt` -> `c:hello.txt` ).
`root` is not normalized, and `path` is normalized.
So `0 != path.indexOf(root)` at line 68 become to `false`

Sorry my English is poor.
