Using ON_COMMAND_RANGE and ON_UPDATE_COMMAND_UI_RANGE

The ON_COMMAND_RANGE and ON_UPDATE_COMMAND_UI_RANGE macros are useful when you want to treat a group of commands similarly. In this case, it's the commands for changing list view style. The command IDs must be contiguous, and you must specify the lower one first.
