Remove -s option in catwin32

-s option is used to sort all cnt files by date.

Default, catwin32 just merge all cnt files according to how they appeare in arguments list.
So, if cnts in argument list are not sorted, win2sac_32 will report a 'time is not sorted'
error.

-s option is important if cnts are not sorted.

In this script, if all works fine, the cnt are sorted by python sorted() function,
thus -s option is no longer needed.

Removing -s option from catwin32 helps speeding up.
