This patch will switch cursor to DragCopy when a user enters a widget
while dragging file(s), giving them a visual clue that it *might* be
dropped into this widget.
This is a rather naive approach, as the cursor icon will change for any
kind of file, as currently programs don't know the drag contents before
dropping it. But after all I think it's better than nothing. :^)
Make the link between SQLStudio and the SQLServer so that statements
written in the editor window are executed by LibSQL when the 'Run'
button is clicked.
Add the necessary GUI elements (button, table) so that one can click a
button to run the currently-open script, and see the results in a
user-friendly table.
