Bump angular to 4+, update year to 2017, HTML output for build via webpack

[mcescalante]

Changes:

• Bump Angular and some other dependencies to latest versions
• Update angular2-in-memory-web-api to angular-in-memory-web-api to reflect latest package changes (package name changed, see https://www.npmjs.com/package/angular2-in-memory-web-api)
• Remove bootstrap from dependencies (it's not linked or used anywhere)
• Add html-webpack-plugin and plugin to webpack.config.js so that npm run build outputs a working index.html file.
• Update year to 2017 in the index

I have tested bumped versions with a fresh clone. Happy to make additional changes if needed for this PR!

I can confirm this works. Just deployed my package on a server after I merged these changes. Thanks!

@pascal08 if you are using this base and want Angular 4+ and other updated dependencies, I just added another commit that updates dependencies 😄

@mcescalante I just merged your changes and bumped my project to Angular 4. Works like a charm. This should be merged!
