Merge lp:~widelands-dev/widelands/remove_nocom_logs_campaign_data into lp:widelands

[GunChleoc]

Removed logs in campaign data that are no longer needed. Made some strings const.

[Benedikt Straub (nordfriese)]

Compiled and tested, works as it should.
Code changes look good to me.

review: Approve (review, test)

[GunChleoc (gunchleoc)]
