Code review comment for lp:~widelands-dev/widelands/remove_update

I find update annoying and difficult too, so I'm all for it. I expect that the added CPU load won't increase for long games, so I think we can afford the extra CPU time - the recent graphics changes have already saved a lot, so we'll still be better off than we were before you started working on the graphics.

Code LGTM, just 1 question. Not tested yet.
