(svn r1302) -Fix: [ 1091655 ] In some older maps somehow water is owned by

 OWNER_NONE instead of OWNER_WATER.
-Fix: On InitializeLandscape the map was made MP_WATER, but OWNER_NONE. 
 When ConvertGroundTilesIntoWaterTiles() is not called, this gives big 
 problems (see above). Now the owner is set to OWNER_WATER by default.
