Description

Closes #1557

BREAKING CHANGE: For webpack bundler, css-modules will be enabled for *.module.[ext] files. The previous *.[ext]?module usage is no longer supported.

[meteorlxy]

@Mister-Hope - It seems that the current ?module usage is not working in webpack. Could you help to take a look?
