getIconForFile case sensitive

[justin-coberly]

When parsing languages like R where the extension is typically uppercase .R instead of .r, getIconForFile() returns a default icon rather than the correct R icon.

This pattern continues for .SVG, .TXT, etc.

Is it reasonable to lowercase the filepath / extension passed in to limit case sensitivity issues?
