Serve all libraries and possibly CSS locally about rzl-homepage

Well the "younger web-hipster generation" (namely @xandy) told me that it is a good idea to use the CDN versions of all "big, well-known" JS libs and have an auto-fallback when the CDN is unreachable.
Because of caching. Most browsers will already have bootstrap and all that loaded anyways ==> faster page load.

I know these args, I still prefer having everything bundled. An increased initial loading time really does not matter, we're not Google.

This is a total bullshit argument for people who have no clue how this stuff works and just cover up googles TRACK-IT-ALL Policy :-P

1. Requests of your browser to resolve the resources are issued in parallel, not one after another. The bottleneck of a pageload is not 95kB jquery. -> Usually no effect on page load speed.
2. This applies only for the first load of the page. At least after the second click the local version of jquery is already cached -> absolutly no difference to CDN providers.
3. The real world: go on and measure this ;-) the last time I tried it with regular webpages the gain for that single resource would be 1/4 of the time, so talking about jquery it is ~ 50ms. not that impressive if the overall page load is ~ 2sek.
