Rewrite of frontendWorker.js, HD support for ZDF, jquery.min
Because of rejection by mozilla I had to rewrite the way the frontend is
built - it is no longer built using .html(), it is now built by native and
pure DOM-manipulation. These might not be pretty but hopefully Mozilla
likes this version more.
Furthermore there is now support for the HD videos of ZDF - also there are
just a few of these.
Also I changed from jquery.1.10 back to jquery.1.10.min.
