Andreas Kling cfcb38dff1 WindowServer+LibGUI: Add data_type and data fields to drag operations
These fields are intended to carry the real meat of a drag operation,
and the "text" is just for what we show on screen (alongside the cursor
during the actual drag.)

The data field is just a String for now, but in the future we should
make it something more flexible.
