[r9544] land industry chain filter on the factory edit dialog is broken

[RESTRICTED ACCOUNT]

I think the land industry chain is correct to include the green lettered industries.
I noticed this because the filter button happened to be further broken in extended.

I suspect that !desc->is_consumer_only() is correct.

This check has been there for a long time (>14 years). So it seems to be intended (?)

green industries = pure producers without any input

land chain = pure consumers not placed in cities

Thank you for confirmation.
I jumped to the conclusion. 
It isn't a filter option, but a trigger button. I will correct the Japanese translation to make it less misleading.
