Add basic font families. For now, we use know-how from the current editor
and we use the same list of fonts as were used in the current editor

We don't reset font family on any level, so there is no need to
bubble the setting using a preprocessor and render the inline styles
explicitly in every block.
In this commit, I change how font-family settings are distributed/rendered
in the email renderer. In the new approach, we rely on class names defining font-family
and a generated CSS sheet with font-family definitions.
We apply the font-family CSS by inlining CSS rules for families in the later phase of
rendering after all individual blocks are processed.

When a newsletter gets deleted in the Newsletter Repository the associated SendingQueueEntity gets removed.
This can happen and afterwards the SendingTask gets deleted. In these cases, we catch the error that
the entity can not be removed and continue the process.

I opted to remove testItDeletesQueueWhenNewsletterIsNotFound() as I
wasn't sure how to recreate this test using Doctrine and I found out
that it was actually not working. The call to
$this->newslettersRepository->bulkDelete() was deleting the sending
queue entry and not SendingQueue::deleteTaskIfNewsletterDoesNotExist().
