fixed SplitDelimiter parser regex, it does no more consider
non-whitespaces (\S+?) as the option name but anything
before the delimiter (.+?), this fixes bug rt.cpan.org#36607,
the fix of 2.39 were not sufficient. Thanks to
Jeffrey Ratcliffe for pointing it out.added new parameter -SaveSorted. The default value is 0,
that means configs will be saved unsorted (as always),
however if you want to save it sorted, turn this parameter
to 1. Thanks to Herbert Breunung for the hint.added complexity test, which checks a combination
of various complex features of the parser.
