Small things to add/update in descriptions/details

[MatthewCline]

A list of things that should be added to or updated in the descriptions or details of various items and materials:

• That airflow tiles and mesh tiles don't block light.
• That doors can be placed horizontally by rotating them.
• Say how much of a speed boost plain tiles give, and also how much (if any) speed boost is given by special tiles (farm tiles, mesh tiles, etc)
• Say how much slower dupes move up and down ladders compared to horizontal movement, or explicitly say there is no penalty if there isn't any.
• Say how much of a speed bonus plastic ladders give.
• The steam turbine should say the minimum temperature of steam it needs, so it will be clear that it can't be powered by steam geysers.
• Wash basins should say how quickly pure water is converted to polluted water.
• Ore scrubbers should say how much chlorine is consumed per use.
• "Polluted oxygen" should use a different description that "[adjective] toxic".  Possibilities to use instead of "toxic" are "infectious", "germ laden" or "germ ridden".
• Explicitly note in the liquid pump that pumping liquids against gravity does not take extra power.
• Note that liquid in pipes is unaffected by gravity.
