@malsa/iconfont-plugin-webpack

This fork made because plugin is not supported anymore, but we need woff2 support

What was made:

1. Updated dependencies version
2. Added support for woff2 build
3. Changed default template to more suitable for skinclub build
4. Add cache busting for fonts
5. Fixed font absolute paths
6. Fixed unicode for icons
7. Fixed multiple inclusions of font-face
8. Dropped IE6 support
