Busy indicator

I just added a busy indicator to the status line at the bottom. This indicator shows when the CPU is running a user program (or running in kernel mode on behalf of a user program).

I shifted the other status indicators (shift, 2nd, diamond, etc) to put it next to the battery indicator:

It's not the best-looking status icon, but can you do better? (Really, if you can draw a better-looking one, send it my way!)

Update: I changed the icon to an hourglass which I think looks better. Still, if you want to draw a better one, let me see it! I also could use a better-looking icon for the "hand" status. Mine looks like a claw. :)
