Added control over how filenames are written to the DSZLOG: via the sexyz.ini

file, [DSZLOG] section, the "Path" key controls whether the full path is
logged, "Short" controls whether the Micros~1 shortened path/filename is logged
(on Windows only), and "Quotes" controls whether the filename is logged in
double-quotes (for EleBBS long filename compatibility).
The "Quotes" feature can also be enabled with the "-quotes" command-line
option.
Updated copyright dates.
