EditorConfig should recognize 'none' value for .editorconfig settings

There's a convention in EditorConfig-styled projects, that when you want to overall prefer a certain style (e.g. indent_size=4) for *most* filetypes, but skip checking for certain filetypes, to set indent_size=none for the ones to skip.

However, the EditorConfig plugin bundled with IntelliJ doesn't recognize 'none' values, and raises a warning. Could we inform IntelliJ's EditorConfig plugin of this convention, to behave more nicely out of the box?
