Fixes and optimization

After releasing of 4th era, several issues showed up, so we did our best to sort these out.

Aside from fixing bugs, I've managed to optimize some parts of Mashinky's game logic, so the performance on lower spec. pcs and also when the game speed is set to higher value.

Full changelist can be seen here:

Optimizations

• There are 3 areas I've improved performance (On screen news, bit arrays used for various AI and signals alghoritms and computation of train wheels position).
  

Fixes

• Sometimes old saves didn't get any of new quests
  
• When cloning unavailable trains
  
• Game creates SAVES directory if not exists
  
• Potential fixes for rare corrupted saving bug
  
• Wrong onboard camera directions when train flipped
  
• Removing tool removes also high speed track stations
  
• Rare crash with selecting / removing building
  
• Adding upgrades to more than 256 stations used
  
• Rare issue with era quests
  
• Crash when removing station still present in a route list
  
• Storage full message cool-down prolonged 5->15 minutes, train lost starving message prolonged 1->3 minutes
  
• New localized texts version
  
• Bangle model flipped
  
• Bulldozer sound tuned down by ~9dB
  
• Too much snow on rails and roads
  

Best,
Jan
