Version 1.0.2

• Depend on polyfill-library instead of polyfill-service (#12, #14)
  polyfill-library is a new package that contains only the polyfills, no webserver stuff. Furthermore, it ships with precompiled polyfills, so the heavy postinstall script is gone.
• Very basic dependency handling (91d8d1c): Whenever a polyfill is configured to depend on another polyfill that starts with an underscore (i.e. a helper function), then the dependency is automatically included in the output.
  For example, the Math.log2 polyfill (and many others) depend on the helper function CreateMethodProperty which is provided in the _ESAbstract.CreateMethodProperty polyfill. Those helper polyfills are now included automatically when they are needed.
  Other dependencies, e.g. Promise.prototype.finally depending on Promise and Function.prototype.bind are not yet handled (see issue #8)
• Fix problem when webpack output.publicPath is not set (#11, #13)
