NPM package updates

This release should now solve all the npm issues and package should now work consistently with both webpack and browserify.

Updates:

• Removed the pre-transpiled code, as this causes an error with the runtime-only build which could lead to confusion.
• Reset the main file back to src/star-rating.vue so these will now need to be compiled.
• Checked that component compiles with both webpack/vue-loader/babel-loader and browserify/vueify/babelify build configurations.
