Get Bugs from Server

The panel is now created by injecting markup into the browser's multiView panel. The bug panel HTML structure was cleaned up and a proper user object made. Bug data is pulled from the server and rendered to the page. It's super neat-o. Will resolve issue #4: Give bug categories expand/collapse functionality. Will resolve issue #2: Link bug summary anchor to the bug's page on the server. Will resolve issue #5: Get bug lists for given user. Categories collapse and expand so that one category may remain open and clicking an open category closes it. Will resolve issue #9: To Fix category returns 400 error.
