[horde] Javascript / Frontend refactoring: Tester wanted

[Ralf Lang]

Hello,

I am looking for a brave soul who is willing to apply three big patches to
their Horde javascript

refactor/vanilla js migration by ralflang · Pull Request #30 ·
horde/kronolith <https://github.com/horde/kronolith/pull/30/changes>
refactor: Convert many helper files from PrototypeJS to vanilla JS by
ralflang · Pull Request #32 · horde/imp
<https://github.com/horde/imp/pull/32/changes>
refactor/vanilla js migration by ralflang · Pull Request #64 · horde/base
<https://github.com/horde/base/pull/64/changes>

and test drive them for a while if they see anything breaking.

These patches do not introduce new features. They try to do the same thing
as before, but eliminate reliance on an outdated javascript framework which
we want to eventually phase out.

So we analyzed what would be the most safe changes to do first. Things
Javascript couldn't natively do or at least not in all then-mainstream
browsers when Horde 5 was new. Things which should now work reliably and
out of the box in all half way modern browsers.

If we see this works out, we can do a next wave. If we see it's a quagmire,
we won't pursue this angle and need to come up with another strategy.

Regards

Ralf
