Make the Grove web client look like this

• Only show the user name and avatar for the first message in a group of messages by that user.
• Indent the messages so they all start at the same spot.
• Use Shift-Up and Shift-Down to switch between channels.
• Focus the message input field whenever you click anywhere in the window.
• Eliminate the annoying image flash between when it's inserted and when it's resized.
