Use webpack-merge to reintegrate mobile conf files with webpack.base.conf.js

[jgaehring]

I went back and found the tutorial Alex used to initialize the project and setup the Webpack configuration: "Making work the Vue.js webpack template with cordova". I think I've found the problem with this setup which is leading to the duplication I mentioned in #14 (comment).

The tutorial goes against Webpack best practices by copying the webpack.base.conf.js file itself and making changes in the copy, instead of using webpack-merge. The build-mobile script then points to the copy, not the base, which is now wholly ignored, kinda defeating the purpose of a base configuration. Found a good article on using merge: "Composing Configuration".

Merging the mobile conf wasn't strictly necessary, but this issue is resolved by /issues/8. Still a little work should be done to tidy up the native Webpack config, which can be addressed in #22 .
