(svn r13317) -Codechange: make news messages use a linked list instead of a moving circular buffer. This makes it possible to store more news messages in the history. Based on a patch by Cirdan.
-Codechange: the number of news messages is reduced by removing every news message that is a configurable amount older than when it would not be shown in the newspaper popup/ticker, which is e.g. a month for industry production changes and half a year for subsidy offers. As a result the more important messages will stay longer in the message history (if longer than 30 messages).
