Display projects with code search result

Description

Display a list of projects in the projects search results tab, which correspond to code search hits. This feature would allow quick scanning of projects which match. An example is finding projects which reference a package with a know security issue to patch. It also allows developers to drill down on their results, particularly when there are a large number of hits in each project.

For example, [Kiln] (http://help.fogcreek.com/8210/searching-in-kiln) displays a list of repositories which contain hits in the top left.
