Make options Partial<Options> (#141)

* Make options Partial<Options>

When working with webpack.config.ts ts complains when you try to pass a partial object literal.
This fixes that.

* Fixed the build.

Had not ran a full build and test before.
Had just quickly done an edit to make the webpack file to stop complaining, was hoping it would pass the auto build.

* Ready release
