This fixes some more tiny things.

one, this pane for chat:

is now contained w/in the pane it's in. If you look back at old screenshots, it was stretching outside of the pane. Interestinglyt, the text DID NOT, but the textarea did. That's fixed now.

Here's a screenshot of the way it USED to look. Notice it stretching off the side of the pane:

Secondly, i tinkered w/ the horizontal and vertical resize things. they have a hover over now so they change color, are also easier to find, and are SLIGHTLY fatter than they were.

Third, and this is the main thing I was working on. I noticed that the STDOUT area clears after each execution - so if you like have the ExecAgent up - ask it to do something, then ask it to do something else it clears between those two messages. Now, we have a running log of it. See screenshot below. There's also a little message at the top about the # of runs that are in this session and the stuff changes from running to run to last run which is kind of nifty. As you can see, it works w/ Rich doesn't screw that up.

I also tinkered a tiny bit w/ the opacity of the background URSA logo but I can't really figure out how to make it look good so I stopped and left it alone.
