Changes on unadf.c by Galt Barber, California.

- extended unadf.c to set the date/time on files and directories extracted. 
- Platform: any unix/linux should work. It uses mktime() and utime() functions. I compiled it under cygwin.

- double quotes for MKDIR to support embedded white spaces
- Many parts of the Windows OS code seem to use a time value that starts at 1980 (NTFS itself seems to support older dates, 
 but not the Windows GUI code itself), so in my most recent version of unadf.c, if I see any year less than 1980 in the set-file-date
 routine, I just substitute 1980 for it creating a floor value of 1980 for the year.  This seems to help Windows very much.

 - I found that windows does not tolerate filenames that end in either period "." or space " ".
 (again I am talking about the GUI, not NTFS). Since I had a number of these, it seemed
 worth the extra hassle for doing it programmatically.
- I also fixed some bugs in the handling of the processFile routine.
- I added some more error messages, and tweaked the output to look slightly better.
- Did a little more testing.
- Did a little code-cleanup too.
