Re-saved diffusion file to get rid of Chemical Reactions reference.
Removed space in URL that caused model to fail to load.

ChemicalReactions: fix a bug causing incorrect bonds exchange

ChemicalRactions: add a new interactive presenting water reaction

[#56872046]

It replaces old "Simplest Hydrogen-Oxygen Reaction" which wasn't
working even in Classic MW, so wasn't useful at all.
Rename "Simplest Hydrogen-Oxygen Reaction" models and interactive

[#56872046]

as in fact it isn't the simples possible reaction. It's a medium
complexity model, quite good for testing though.

Refactor / fix "radial bonds results", calculate it in modeler

[#50086303] [#56871868]

... instead of in engine. Previous implementation was incorrect
anyway, causing [#56871868] bug, so this is not only refactoring, but
also a bug fix.

However I still think that current pattern pretty repetitive and
approach similar to objects-collections would help a lot. ;)

Fix radial bonds rendering, update more properties on "tick" event

[#50086303] [#56871868]

...as many radial bonds properties can be changed during "tick",
e.g. by chemical reactions plugin.

In general I'm starting to think that "tick" event is evil, because
it's too generic - view has no idea what to update when this event is
being triggered (this knowledge is derived from knowledge about
implementation and engine internals).

QD: Reduce default lifetime: Should be fixed better

This should use a simple cut-off lifetime, as in the original
