Changes in version 11.2

The -nosubs command-line argument is now parsed before traversing folders for image files (had been parsed afterwards, making it ineffective). Note that this option must be chosen in the Select window by clearing the checkbox before adding folders to view via the folder dialog, as a new balloon tip says.
Fixed a memory leak that caused out-of-memory crash.
Timer is now stopped when an error occurs during display, to prevent repeat of error message.
Test and warning message added for invalid command-argument keywords.
Improved and documented command-line options; see the readme.txt file, or app-startup source code.
Various internal changes, and some procedures renamed.
