Move common icons option to file style struct 

All four of the view mode command-line argument parsers tested for the --icons option. Because it was common, the behaviour has been moved to the struct that handles file styles, meaning it can be parsed in one place.

This is a better place for it, as the icons are to do with the file name, not the view. It also means that the lines view has no options left for it, which is fitting.
