Standard sidebar for individual issues

Each issue page should have a descriptive sidebar that helps categorize the issue (using one or more categories), provides a map of where the issue fits within its category, and provides a short description of how well-developed the issue page is.

"Well-developed" will require some definition and consensus. Some suggested axes to look at when determining overall quality:
* Number of sources cited
* Quality of sources cited (difficult to measure!)
* Quality of analysis (also difficult to measure)
* Stylistic quality (writing, links to other pages, images, etc)
