Title: Add support for page margins to worksheet.

I needed to specify custom page margins, so I added support for the PageMargin element :-)

For backward compatibility I made sure that the PageMargin element only gets added to the Worksheet’s XML if custom margin values have been specified explicitly. (The element, if present, needs to specify all six possible margins – values not specified by the user are set to defaults taken from MS Excel for Mac 2011).
