Code review comment for lp:~widelands-dev/widelands/economy-target-profiles

I made the save dialog modal, my mistake. This was supposed to ensure that only one save window is open at the time and the parent window won´t disappear while it´s open.
Now I ensure this another way; the game progresses normally and input isn´t blocked.
The last revision now has a strange behaviour though that the save window doesn´t close by itself if you destroy the last flag of the economy, which I don´t understand yet…
