Code review comment for lp:~leeturner/quam-plures/num_blogs_config

Gonna make this as a comment only for the moment. The text on the User Profile page isn't very good IMHO, but I dunno what I think would be better. The thing is my first thought was "why would I limit how many - I want all of them displayed" even though I knew in my head it was referring to how many get displayed before a dropdown menu is created for all blogs beyond the number entered. I'll throw some ideas (if I have any) for the label and note out in the forums.

Otherwise works as advertised and doesn't cause problems and adds coolness so I'm totally okay with marking this "yay+" or whatever means good and doing the merge.
