Add prefilters and tasks to the default screen type.

When creating a new subject the default screen type assigned (master detail) does not contain the most frequent used components, namely tasks and prefilters. More often then not this results in having to choose a different screen type. If you have no prefilters/tasks the component is not shown so there is no harm done in adding these components. 

My suggested fix: add a new default screen type master detail with preftilters and tasks. Have this as default for any new subject instead. This will keep current screens using master detail in tact but will improve the user friendliness.
