create vendor bundle to remove jsdelivr cdn

[zivillian]

This PR creates a vendor.min.css and vendor.min.js from the already installed node modules using the existing grunt tasks.

Since the installed bootstrap module is 3.4.1 this also updates the bootstrap.min.js from 3.3.7 to 3.4.1

fixes #1056

Changes look good! thanks for the pr. We might have to wait a tiny bit to merge this until our svelte branch is merged in as it will cause quite the conflict going first.

@zivillian I don't seem to be able to make changes to your branch. We just merged in the svelte changes which makes ClientApp the svelte app and ClientApp.angular the angular app. Would it be possible for you to apply this patch to the ClientApp.angular folder.

@zivillian looks like there is an issue with the font awesome fonts not being loaded

host/fonts/fontawesome-webfont.ttf?v=4.7.0 results in a 404.

Any chance you could take a look at this.
