Change saved <summary> tag back to English

This ensures loading a 2.4 save in the English-only 2.3 or earlier
doesn't result in missing characters because a translated area name
appears in the save file. We are not reading from <summary> anymore
in 2.4.

The way this is done is by not translating the area names inside
mapclass::currentarea(), but at the callsites other than the one which
saves the <summary>.
