Avoid output of deprecations?

[s2b]

Other widespread PHP libraries seem to use the silencing operator @ when triggering exceptions. We should probably do the same in Fluid v4. We should check how this affects TYPO3's deprecation logs and test suite.

core does this: TYPO3/typo3@8140ec4
the code was moved around a bit over time, but it's still same strategy: log deprecations, even if it has the STFU operator.

I just tested this with phpunit's default error handler: The deprecation with STFU operator in fact is ignored by phpunit. TYPO3 on the other hand logs both kinds of deprecations.

So I would argue to only add the operator to deprecations that are added after a major release and to leave those for Fluid v4 without the operator.

What do you think?

Sounds like a good trade-off. Let's see if we can manage to stick to this ;)
