Improvement of new tags view

**Addition:** The tags view was improved for functionality and the React table was tested with sample data. The create, upload, and download dialogs have been fixed so that they have proper text. Finally, the sub menus now will show up when in the tags view. Previously, only the top menu bar would show up.

**Other Information:** The TODO comments represent changes that still need to carried out for this view. Most of this can only be accomplished with a controller and model.
