Add --single-file-directory option: create single directory with all linked files.

Browse source 
This new option copies all files to the directory specified as an argument
to the --single-file-directory option, and also creates dummy shorter
filenames for the files.

This feature was implemented to get around a problem found when zip'ing
the spreadsheet up with the supporting files for users on Windows.  The
Windows users encounter the error 0x80010135 related to some of the ZIP
files going beyond the maximum path name length on windows.  Apparently,
opening ZIP files with long path names just doesn't work on Microsoft
systems.  I've suggested our accountants switch to a Free Software
operating system, but they declined.
