Package using UMD to make it work in a Typescript/Webpack project (#125)

* Fix #93. I can use the NPM package in a Typescript/Webpack project

Changed the library type to UMD.
> libraryTarget: 'umd' - This exposes your library under all the module
definitions, allowing it to work with CommonJS, AMD and as global
variable.
