(svn r22629) -Fix [FS#4599]: Remove all usages of the ErrorRefStack. It was continuously overwritten by e.g. industry prospection without closing the old error window; also StopTextRefStackUsage() was not called for errors returned by commands (which caused FS#4599). Now return in the CommandCost result whether the textref stack needs to be used, and store a copy of the stack values in the error window just like for the normal string parameters.
