Names of certain technologies / buildings don't display correctly

[Quizer85]

The names of certain technologies and buildings don't appear to be properly defined and are displayed in-game with their lua strings, such as "technology-name.extended-solar-energy-4". This includes but may not be limited to the following:

• Solar panel variations (technologies)
• Chemical plants Mk II and Mk III (buildings)
• Oil refineries Mk II and Mk III (buildings)
• Molten material processing (technologies, called "technology-name.molten-machine")
• High-powered boilers (technologies)

I'll try to add further instances of this problem if I find more.

• Tungsten wall gate (building; these also need a proper gate graphic, as do the sand walls)
