Add project specific Issue Finder view

[ondrae]

Description

We got a low priority request from @spjika to show the issues from specific projects. We can't do this yet and should add the ability. A few different hurdles in setting this up.

• The CfAPI is ephemeral, meaning the project ids aren't guaranteed to not change in the future. We would want a Brigade to hardcode in a link like http://codeforamerica.org/api/projects/4664 in their website. Instead using the GitHub url would work. The closest you can get is using search like http://codeforamerica.org/api/organizations/Code-for-San-Francisco/projects?q=https://github.com/sfbrigade/sfbrigade.github.io
• The Issue Finder expects issues to be the top level response. Right now, specific projects don't have an /issues endpoint, so the Issue Finder code would need to know to navigate down to the issues.

I called this low priority, because people can easily roll their own version of this feature using either the CfAPI or GitHub's API.

Tasks

• On the embed form if a specific group is chosen, then show another drop down which lists all of that groups projects.
• If a specific project is chose, then have the widget url be something like https://www.codeforamerica.org/geeks/civicissues/widget?organization_name=Code-for-San-Francisco&project=https://github.com/sfbrigade/sfbrigade.github.io
• Have that url ask the CfAPI for http://codeforamerica.org/api/organizations/Code-for-San-Francisco/projects?q=https://github.com/sfbrigade/sfbrigade.github.io
• The Issue Finder will need to know to look for response['objects']['issues'] rather than just response['objects']
