Resolve console error; clarify disabled modal section text

I noticed a console error every time I clicked on the "Views", "Storage", etc. section on an instance view. 

I thought this might have been an issue so I investigated, but it turns out they're just disabled.

I made the following changes:

* Rather than use `javascript:void()` on disabled links, I set them to `href="#"` which has the same effect as far as I can tell, without JavaScript (and the console error).
* I added the text "(Disabled)" to the disabled sections, so that users would be aware that they're disabled rather than thinking there might be an issue (as I did).

I know this isn't as relevant, but thanks for your efforts on this great application.
