Hi all,

Mainly polish in this one. Let me know if I went overboard with the UI animations.

Additions

• Added animated transitions to all GUI.
  

Fixes

• Fixed spare track duplicates & mirrors not saving correctly.
  
• Fixed failed assemblies partially leaving the designer, with no way to return, locking the game. Reproduceable on tracks with no roadwheels.
  
• Steering with cruise control now scales with the current cruise level.
  

Changes

• Reworked scenario selection screen. Making it more open to additional scenarios and give more info on what you're playing.
  
• Updated all starter blueprints.
  
• Increased handling of twin transmissions at speeds. Fixed an error which allowed the track to move faster than the current engine-gear speed.
  
• Clutch braking now gradually applies the brakes during drive+steer, instead of purely disengaging the clutch.
  

Starting on scenarios next.
