Code review comment for lp:~james-w/indicator-applet/messages-icons

Hi,

This change adds images to the servers in indicator-messages
based on the icon from the desktop file if available.

They are not in the drawing at https://wiki.ubuntu.com/MessagingMenu
but we have the information, and I think it looks good and helps
quickly identify the app you are looking for, and ties in the
servers to the main menu entries, tasklist entries and title bar
icon.

Thanks,

James
