Good evening.

I didn't like the scrolling in the battlescape, so I changed it. I thought:

1. The camera movement should slow down quicker than it speeds up. This means it actually stops where you meant it to rather than a screen later. I was having trouble with noticing that the scrolling was slowing down. This meant that I would move my mouse away from the edge of the screen, not notice that it is slowing down, and hit the other edge of the screen, causing it to scroll the other way again. Having it slow down quicker prevents this.
2. The scroll speed should be adjusted according to the zoom level, so that it isn't just a blur at high zoom, or annoyingly slow when zoomed out.

Very simple changes. Here is a patch:
