This probably works better as an app than an extension

I felt lucky to hear this extension mentioned in the elastic search irc channel, but was sort of bummed when I saw that it would always be sitting just to the right of my search bar.

The extension could probably serve all of it's useful purposes as a packaged app, while requiring less scary permissions and not taking up valuable space on the primary chrome.

Please consider these changes, which include updates to the icons to match the new elastic search site.
