(svn r10347) -Fix [FS#948]: industries with a very low production could never recover when using smooth economy.
-Fix: in smooth economy producing industries could not close, whereas they could close in non-smooth economy.
-Fix: in smooth economy the "do not increase production" flag of industries was ignored.
