Selfhost JS and CSS dependencies

Selfhosting 3rd party JS and CSS

Currently we're pulling Javascript and CSS files from various third party sources. I'd like to minimize those dependencies by having NPM include them, uglifying them using Grunt and including them into the master.min.js file. This should preferrably be also done with the CSS.

Things to selfhost here:

• Angular from CDNJS
• JQuery from CDNJS
• Bootstrap CSS from MaxCDN
• Bootstrap JS from MaxCDN
• Angular-Sanitize from CDNJS
• Ng-Table CSS from unpkg
• Ng-Table JS from unpkg
• Sweetalert JS from CDNJS
• Sweetalert CSS from CDNJS

I think this would probably increase privacy a bit. Performance shouldn't be hurt too bad (if at all).

While we're at it we might aswell directly include all the JS files after they're all combined/uglified like here: Link. I think this will be OK performance wise, since it's a single page application (will still run performance comparisons, though).
