For Typescript projects it'd be useful to allow main.ts as the entry point, instead of requiring main.js in all projects. One method of providing this functionality is to use the main property of package.json. This would allow developers to choose any main file, such as main.ts or main.coffee even.

If the main property in package.json isn't provided then the get-webpack-config could fall back to main.js.

Another option could be to add a new optional property to .fusionrc.js if we feel package.json's main property is not the right place.
