Support of csv files with .xls extension

Hi Kohei, great that you responded!

Could you also take a look at 
https://bugs.freedesktop.org/show_bug.cgi?id=70100. There is a file which is 
detected by Excel 2010 as 'Excel 2' sheet and LO also sets the excel4 filter, 
but it fails in isExcel40 function from sc/source/ui/unoobj/exceldetect.cxx 
because it has a value like in BIFF5.

Thanks in advance,
Maxim Monastirsky
