CSS Modules is forced even without `.module` extension

[enzoferey]

Hi !

When using the cssmodules flag for SASS files, I noticed that even if the file doesn't have the .module extension it still bundles it as it was a CSS module. This means we can't use in the same project both CSS Modules and normal CSS.

Maybe #6 fixes it ?

Hello,
I also would like this feature. Is there any release scheduled ?
Thanks
