Right, I have a few more changes up on Github. There are very few functional changes in this, but a lot of minor changes to variable names, comments, etc. to bring us a bit closer to Standard.
There is, however, a backwards incompatible change to reading xml saves; this reverts an accidental backwards incompatible change made when James originally applied spieler->player to Extended. The change concerns whether "spieler" or "player" is the name of the xml tag in xml saves. I think it's simplest just to make a breaking change since I think xml saves are only really used by people wanting to run analysis on a save using an external tool (there's no other reason I can see to change the default). If this does cause problems, however, it should be possible to write some extra code to accept both versions (during loading).
