    gedit-pango.c: Quote font-family CSS string
    
    Currently the css string generated by
    gedit_pango_font_description_to_css() does not quote the font-family
    string. If the font family name contains space, gtk may fail to parse
    the css string correctly (e.g. "Courier 10 Pitch").
    
    To fix this issue, simly add double quotes to the font name. This fix
    should work for font names that do not contain special character (e.g.
    quotation marks, backslashes, etc.)
