Now store and send the path used (using x=x1,x2,.. and y=y1,y2.. in [move])
This currently break compatibility with replay done with RC1 (if they worked)
I will try to restore backward compatibility in next commit.
PS: This commit is a small variation of the patch posted in the bugreport
Break the dependency of string_utils.cpp on formula ai since it pulls
in practically everything else as result. Since servers use
string_utils.cpp this is unacceptable.
...move into separate cpp/hpp pair. The code under src/ was modified
mainly using a global search-and-replace. This change allows reducing
code dependencies and gets rid of inner-class confusion (parts of the
code had to use "location" when referring to gamemap::location, it is
now consistent across the codebase.)
