Source/WebCore: 

To support drag-and-drop to the desktop and other windows applications,
we need to support the fileDescriptor and fileContentZero clipboard formats.
This patch adds the support for serializing these types across the process boundary.
It also fixes a regression introduced by r70914, that was causing the content of the
shortcut files to be corrupted. Using ascii() to convert from String to CString was
causing '\n' and '\r' to be replaced with '?'.
