Title: Update bg_color in conditional formatting

Conditional formatting for background color fills is different for DXF. This must be undocumented and is quite annoying. I verified the behavior in Excel 2010 Mac and Windows. I didn't understand why background colors were not being applied even though the style was being applied for conditional formatting. Looking at styles.xml I saw that it is different in a file created by Excel. I have updated the code to reflect it and tested in Mac and Windows.
