@ingorichter
Includes:
* [Sprint 41 changes](https://github.com/adobe/brackets/compare/sprint-40...release#diff-84)
* Some minor things requested in #8000
* Fixes to `search-summary.html` in order to correctly render the space (similar to #8206)
In the English translation, this one was changed from `All...` to `Batch...`, which aren't the same either. I'd say these aren't the same ("batch" is more like "selected" = "ausgewählt").

The reason for the change was probably that you can select which results will be replaced, so it needn't be "All".

Another possibility would be "Ausgewählte ersetzen", but it's possibly too long.
