tdf#35570 Writer: drag and drop rows/columns without overwriting

cells of the target table. Instead, paste rows above or
columns before in the case of enhanced table selection
(clicking in front of the copied rows or columns) or in
the case of wholly selected tables.

At moving (without pressing Ctrl during drag and drop),
remove the originally selected rows or columns instead
of emptying them.
