OS: Linux
When starting from terminal program displays a lot of debug information.
Effect: While debug output is useful is something goes wrong, for normal use it creates more problems, especially when all that information ends up in system logs.
To reproduce:
1. Start XnView MP in terminal and observe terminal output while performing operations in application.
Actual behaviour (bug): Too much information is sent to terminal (stdout)

Expected behaviour: Keep output to stdout minimal by default, but add special flag (e.g. -v or --verbose) to turn on debug output.
