SWORD25: Fix regression in persistence code

The regression was introduced by commit e6ba26ff0d which wrote
coordinates of a rect as unsigned int when they were before written
as signed int. Since the load code was not modified it still expected
signed int. They are now again written as signed int. Any gamed saved
between commit e6ba26ff0d and this commit will therefore be corrupted.
