Subject: [PATCH] work around bug #12450...

(boost issue previously marked as 'upstream problem') by not using
boost iostreams to write directly to disk, instead, write to a
stringstream and thenoutput that to a file. This makes Wesnoth no
longer hang when a save is issued with insufficient disk space.
