Make the html attribute on the blob json call optional
Right now every call which is delivering the information of a blob is also delivering the rendered html for a viewer. As we are doing now the viewers natively in Vue we should have the possibility to exclude the information from the result to save on rendering + payload. This should reduce the loading time significantly.
