Alpha 4.4 V8 for ETK - I Series 0.7

Some texture and geometry tweaks, fixed the broken 4400 lettering, finally added a pulley system to the supercharger

Changed visuals of all intake variants, inspired by BMW M60-M62 engines. Added "early intake" with more power loss on high rpm and a different model

Some updates to the configs, rewritten torque graph (before it made even less torque than the 3.0 and also was unreasonably peaky), custom long blocks and ECUs

Basically entirely changed the torque graph of the engine so not to output unrealistically high torque with stage 2 and 3 internals. This made it much more rev-happy and also increased the maximum NA power available up to 510. Retested the configs accordingly, added the 4400tix supercharged variant. Fixed the exhaust not having afterfire (even the race one), tweaked muffling values to better match those of the i6 exhausts. Added new ECUs specific to the v8 to match the rev-happy nature of it.

Made custom lettering textures. Also removed unnecessary data from .pc config files

Added custom node/beam structure for the engine, sport intake and all V8 exhausts (if you try using I6 exhaust, you get the no exhaust effect)
