Readers / Runners unable to run individual paragraphs in 0.9.0

In version 0.9.0, users who are Readers and Runners of a Notebook can only run the whole notebook and not select the paragraph they wish to run. Readers can only enter a Notebook into the Report view but cannot go into the Default view without Writer permissions. 

In version 0.8.1, readers were able to select each paragraph rather than having the run the whole Notebook, ie they were able to view each Notebook using Default mode but they just couldn't edit the Notebooks.
