Subject: [PATCH] (svn r2173) -Fix: [ 1179380 ] Rail now builds on reserved
 land. Cause by the problem that CMD_ERROR is just the highest bit of the
 return value, but CMD_CLEAR_LANDSCAPE returns a negative value for owned
 land. So the highest bit is set as well. Note to self: Finish Command Patch
