Title: Drag & Drop support of folders (Chrome >= 21)

Chrome 21 implemented the possibility for folder drag & drop.

This patch adds a "relativePath" property to each instance of ``plupload.File``.

Example: http://protonet.github.com/plupload/examples/drag_and_drop.html
More details to the chrome implementation: http://wiki.whatwg.org/wiki/DragAndDropEntries
Chromium issue: http://code.google.com/p/chromium/issues/detail?id=99823

Also this patch makes sure that the default behavior within ``dragover`` is only prevented when the drag contains any files otherwise there will be problems when eg. the ``drop_element`` is a ```` and the user is dragging text around.
