Moved hidden features for Report download buttons under View section.

If a user can view a report they should be able to download a report. Hidden report download features were under Modify section, if user didn't have access to modify/add reports they were getting User not authorized for this task message when trying to download a report.
- Fixed a typo in feature name text.
