Banner is prepending absolute paths

The banner attribute on webpack causing prepending of absolute paths on bundles which leads to this error:
`Error: Cannot find module '/Users/furkantunali/Sites/chantelle-tools/node_modules/source-map-support/register.js'`


Start with the webpack banner configuration and reproduce the reported bundle error using the example in the issue. Inspect the generated bundle to identify why the banner prepends an absolute local path. Done means bundles no longer contain machine-specific absolute paths and the reported module-resolution error is resolved.
