Comment 6 for bug 1056488

Attached is an updated set of icons.

1. They increase contrast between the chat status color and the
    envelope colors.

2. They add slight spacing around the chat status to make the shapes
    clearer.

Two other bug fixes will also improve the appearance:

3. By mistake, the previous icons were too small and a bit blurry.
    David Calle fixed that yesterday.

4. The "Available" icon appears by default even when you're offline.
    Ken VanDine will fix that soon, so that by default you get just the
    envelope. Bug 1046360

I propose that we look into these icons in more detail for 13.04 and will file and target a bug.
