More flexible Train Stops

• Trains can now stop at any building that has a Train Stop attached. The transfer rate when using a Train Station remains at 1 full car per .5 seconds, otherwise transfer rate is limited to 4 items / second.
  

Trains have been available for a while, but after player feedback I realized I made them too limited. I wanted Trains to fill a niche of high-throughput long distance transport, so I made them carry a lot and load & unload very quickly, but also require a 3x3 Train Station to transfer any items, plus a 1x1 Train Stop logistic block to connect to the station.

However, this means that in pretty cramped layouts trains were not viable - space is at a premium and players just didn't want the hassle of working a the 3x3 Train Station into their layouts. Also, many players were confused why Trains weren't making use of Train Stops (the answer being, they weren't connected to a Train Station).

So I've changed things around so that trains can load or unload at any building. (A Train Stop is still required, as this tells the Train it needs to perform a transfer, but those are 1x1 and fit neatly over rail tiles). However, the rate it can move items when it's not at a Station is just 4 per second.

This should preserve the advantage of long train routes + Train Stations for centralized, large-scale transfer tasks, but add an additional role for trains that they can shuttle goods around a smaller loop. This is particularly useful because trains can carry multiple goods at a time, and can perform both pick up and dropoff. You'll just need to find a way to supply your train with fuel and water.

Additional Balance Changes

• Airship transfer rate increased from 2 items / sec up to 4 items / sec when not at an Airship Dock
  

Bug Fixes

• Fixed bug: Chinese localization would not display correctly on some menus & tooltips
  
• Fixed bug: arrow keys on Build menu would jump around between results instead of navigating up or down
  
• Fixed bug: High throughput, High latency maps could sometimes stop working. Caused by a Farm harvesting action that changed a crop state which then caused an Earth Shrine to apply its regen boost all in the same update loop.
  
• Fixed bug: Trains at a Train Stop flagged for ‘Wait until Empty’ would never resume unloading if had to temporarily pause due to target building being full
  
• Fixed bug: missing text for ‘Preserve Depleted’ option when editing rules for Natural Resources
  
• Fixed bug: Build menu search text would not get cleared after loading a different game
