Waste Power Plant & general improvements

This update contains the following improvements:

• Added Waste Power Plant
• Reduced tidal generator output from 1.5 MW to 1 MW
• Modified Industrial Aid priority order for "high level" industries
• Buffed Relaxed Zoning card to reduce distance by 2 instead of 1
• Added house cost table to Town UI
• Fixed several bugs where card extra information windows tried to read invalid ingame state when opened in the progress menu
• Fixed bug where the Export Negotiation extra info button would crash the game
• Any Import card and ordinary import cards now have extra information windows
• Too few orders notification will no longer appear for trains that will stop automatically
• Altered fuel refinery model to eliminate z fighting with nearby structures
• Revised GREASY.MID
• Fixed a bug where import contracts could not be created after resuming from a Limited Term game over

In addition, the windowing library has changed from GLFW 2.7.9 to GLFW 3.4, bringing the following improvements:

• The game window now has an icon
• Changes to the fullscreen option can now be applied without restarting the game
• Issue where screen resolution was changed for no reason on Linux should be fixed
• Issue where mouse movement was affected by DPI scaling in fullscreen mode on some Windows systems should be fixed
• Mouse cursor will no longer malfunction when using absolute pointing devices (e.g. touch screens) in fullscreen mode
• The default hotkey layout is now more consistent across different keyboard layouts

However:

• Existing custom hotkey settings for users with non-english keyboard layouts have been broken and need to be restored to default or manually recreated
• The game window will take longer to open on some systems

The Waste Power Plant adds a new use for the Waste resource. It is able to generate a good amount of power (18MW peak), but in doing so it burns through Waste exceptionally quickly, so this is not sustainable. However, like the Steam Power Plant, it is able to adapt its output to match the current demand, and remains on standby when demand is met by renewable energy sources. This makes it a viable choice for load balancing when demand is variable.

In addition, Distributrains is now available at a discount due to participation in the Steam Train Fest.
