LCV4.2.18 Hotfix

The third patch for the week has few more important fixes addressing mostly campaign. It will clear up a lot of campaign forecaster confusion too, it now actually seems to be pretty accurate!

[h3]General Fixes & Improvements[/h3]

• Added total historic trim sales to trim's sales tooltip on hub
  
• Fixed techpool having the wrong effect on engineering times
  
• Fixed several forecaster issues that would make for inaccurate predictions
  
• Fixed non-signed-off car projects detracting from sales of existing cars
  
• Fixed car sales numbers on the campaign end screen being shown wrong
  
• Fixed old engines in the campaign hub not disappearing in a reasonable way
  
• Fixed overly large front engine bay on 10sSuper_Cor

More fixes and polish coming next week.
Cheers!
