Outdated 6.0L and 6.7L Diesel for D-Series 1.8 patch, for game 0.19

There has been a few beamng major version releases since I've touched this mod.

Finally had time to patch for the latest version of game 0.19.4

Fixes:
-Exhaust is fixed.
-Fuel tank fixed.
-Now using new/correct engine mesh.
-Differentials configured/show up in menu's like original vehicles do now.
-Fixed missing and incorrect parts for default configs in d-series menu.
-I'm sure there was others

There is a missing feature going forward... I can't seem to get my interior with the diesel...

- 2.75 ratio differentials have been converted to a 3.73 ratio as its a more realistic ratio for trucks.
- Transmission ratios have been modified to avoid being too short for the diff ratio change to 3.73. Re-looked at truck transmission spec sheets for reference.
- There are now two torque converters options for diesel auto transmissions, one for low torque output(non-turbo config) and one for high torque output(turbo config).
- Transmissions have been separated out per engine type(Gas or...

-New diesel idle sound as well as sound config file overhauled
-Updated hp/torque from exhaust power reductions from game update 0.12
-New high flow exhaust part, output ranging from 4hp & 4lb of torque to 11hp & 13lb of torque increase depending on config
-CVT transmission and weighted left and right toolbox for d-series bed. (standard, 300lbs & 600lbs options) cared over from add-on pack, additional add-on pack download no longer needed.
-Overall engine torque has been reduced by about 9%,...

Fixes issues with rear diff and leaking exhaust from engine bay, since the new game update 0.11. Also comes with some sound tweaks.

Rear heavy duty diesel brakes weren't showing up on desired configs. Fixed!

Upgraded brakes now found on the following configs:
Ext_heavy_rwd_diesel
Ext_heavy_4wd_diesel
Crew_heavy_4wd_diesel

H-series(Van) gets diesel engines, transmissions and diff options.
Never seen an ambulance that didn't have a diesel engine,
Heavy duty brakes for diesel upgraded:
Front are about 10% strong and more resistant to brake fade.
Rear are about 20% strong and more resistant to brake fade
Possible high pitch sounds from idle fixed.

Rear brake upgraded more then front as it was desperately needed with a loaded rear end. Brakes still feel balanced and lock up in front first typically.

- Added 3 new stock diesel d-series configurations (Now 5 in total)
- Added turbo spooling sounds
- Stock configurations have had a 8% detune (Attempting to make more realistic for time period)
- More dynamic fuel economy
- Added a 2.75 ratio open diff to rear
- Improved automatic transmissions smoothness while driving at low throttle
- Redline now acts more like a rev governor

- New diesel sounds across all rpm range for diesel 6.0L and 6.7L.
- Converted transmissions to use new beamng update 0.10 standard.
- Fixed problem caused by beamng update 0.10. of auto transmission being slow to up shift.

For bonus content - experimental transmissions and more now.
- added weighted left and right toolbox for d-series bed. (standard, 300lbs & 600lbs options)
This can aid in better rear traction, and also help stabilize the truck when towing heavy trailer (Just an added...

Cleaned up mod folder of conflicts

Cleaned up mod folder and increased engine retarding forces for better engine braking when off throttle.
