supported-formats.txt: clarify ratings legend

Thanks to Helen Flynn for the suggestion.
supported-formats.txt: add note about sorting

This adds a note (to the HTML version only) that you can sort by any of
the columns by clicking on its header.

Thanks to Helen Flynn for the suggestion.

false, ChannelMerger is effectively "disabled" so the isInterleaved()
call is passed to its delegate Reader.

true.

This should fix interleaved image thumbnails displaying incorrectly.
