[EP2] still some missing features/content

[ALIEN31ITA]

Fast Zombie

AttachToVehicle is an input for the fast zombie, since it's missing in Garry's mod, this ruins one of the iconic moments were you get jumpscared by one while driving the car with Alyx, despite the animations that got ported for it it would be a waste.

Model & Textures

Huladoll

is missing 1 animation, used in the final map near the rocket launch sequence

Cargo Containers

they have exlusive textures, this would be problematic since the maps with these models have prop_static's using them too

i will try report any new problem here if it's ok...
