Add person page that displays all the items that are assigned to a person

[muratg]

It can be a URL like: https://projectkissuelist.azurewebsites.net/persons/anurse

It could display the same "person" box as in the kcore page. (perhaps Other Assigned Issues expanded by default.) Later on stats etc. can be added to these "per person" pages.

Turns out this is super duper complicated and/or impossible. There's no API to get this information. There are APIs to get all the items for the current user (not useful), or you can use the search APIs to find all issues (but this is severely rate-limited), or you can do one query for every repo of the org(s) that you care about.

I'm thinking I'll implement the last one, but it's quite costly and slow.
