(webpack loaders) manage images links with query parameters (#398)

When a image link contains query parameter, webpack doesn't
handle it.

e.g. with a link to an .svg file -> .../file.svg?v=1

the file will not be handle by webpack, and the user will get
an error like below.

```
Module parse failed:
/.../node_modules/font-awesome/fonts/fontawesome-webfont.svg?v=4.6.3
Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
```
