Support copying of a single range and pasting it to multiple ranges

Background: Excel supports e.g. copying A1, and pasting it to D3, D5, D9, but Calc doesn't support this operation yet. We should add this support.

Detailed requirement: When the destination ranges are exact multiple of the copied range geometry-wise, allow the paste, otherwise throw an error and abort the paste. For example, when the copied range is A1:A3, and the user wishes to paste it to B5:B10,E8:E13, the paste should proceed. If the user wishes to paste the same range to, say, B5:B11,E8:13, it should throw an error message and abort.

Code pointers: We should be able to add this enhancement just by modifying the code that does pasting. However, if needed, ScViewFunc::CopyToClip() is where the copying of range to the clipboard instance takes place. ScViewFunc::PasteFromClip() handles pasting of cells.

Skills: building, debugging, medium C++, ability to read and understand C++ code
