[0.11.19] Liquid Production isn't shown in production screen

[pcmaster160]

This could be seen as a feature request, but I'd argue it is a bug because producing liquids is production in the same way items are (mining ores shows up in the production tab, so should drilling oil). Liquids don't show up on the production screen, while items do. Nothing major, but still should exist.

Thanks for the report. Yes, it is a feature request and we are aware of this=) Just too many things ... Putting this to not a bug.
