Automatically detect valid stylesheet extensions #72
Description
It could be nice to allow passing stylesheet names without an extension and automatically load any file with a known compatible extension (eg: .css, .sass, .scss, .less) that matches the path. This would allow users to easily change between/support multiple of native CSS, SCSS, LESS, etc. The list of supported extensions could also be configurable, although I don't personally know of any other stylesheet file extensions.
