[patch] New statistics class

[gerw]

This patch introduces statistic_t, which is a small class containing the important parts for statistics. All statistics are now a statistic_t object. In addition, the statistics for world, cities and players are unlimited, i.e. they will save the _complete_ history (The charts show only the last 24 entries).

What is missing:
- a GUI + routines to save the history to a csv file.

Please tell me, if the patch applies fine with Tortoise - then I will publish my little 'git-svn-diff' script.

What an amount of work 

But why did you rename all the variables (ie from karte_t::get_finance_history_year() to karte_t::get_world_history_year) ? Imho the old name is much more descriptive than the new one, which contains even redundant information (ie world, convoi etc).

With the renaming, you would know, what a history you get (since all histories has different entries). The old name get_finance_history_* wasn't better, imho. Renaming it to get_history_{month,year} shouldn't be much effort...

Maybe I got 'inspired' by something like

Code Select Expand

bev += (*i)->get_finance_history_month( 0, HIST_CITICENS );
