Fix panic when dragging text onto a window on Windws (#697) (#711)

Browse source 
* Fix panic when dragging text onto a window on Windws (#697)

* Changed `panic` to `debug` (log) when unknow error occurs in `GetData` while processing a drag-drop / hover event. Plus added appropriate cursor effect if hovered item can not be processed.

* Improved code clarity.

* Add documentation to clarify behaviour of `DroppedFile`, `HoveredFile`, and `HoveredFileCancelled`

* Add period at the end of sentences in documentation.
