[horde] Javascript / Frontend refactoring: Tester wanted

[Ralf Lang]

Hello,

based on your feedback I did upgrades both in the core javascript
foundation and in Kronolith javascript.
We now run a patched prototypejs with a little bridge which allows us to
de-prototypejs all event listeners but not event emitters (they still need
to say "fire" until the last consumers are ported to native events)
The kronolith branch of this activity has been incorporated into the latest
code already.

For IMP I need to do some steps back to make it work correctly with the
changes. So this one stays open for now.

The ultimate goal is to drop prototypejs and migrate to a framework-less
approach in the browser. PrototypeJS mostly solves problems we no longer
have and haven't had for quite some years.

Thank you for providing this testing!
