Generic trade missions have inapropriate success lines.

[solntcev]

At this moment if generic mission (GM_Harvest_Resources.xml) is finished, missiongiver said something like "They had no hope of surviving!" or "They can't have survived that!" (line 3106). Which is rather odd if I just delivered some ore or energy cells.

Is there plans to add more specific lines to missions?
Is there some more generic message that can be used in success mission?

I think line 3041 can be used for it instead.
