Jeep and Overlay

Simple, but yet a bit messy example.

Shows of how to correctly make a jeep and how to make that grabbing thing on the back of it appear.
And it shows how to make alyx jump in and out of it on the same time as you do, and also shows how to make her follow you, but there already is an example of that in the vault.

The example also shows that alyx can ONLY get out of the car IF there are info_nodes nearby.
If they are too far away, alyx will remain in the car after you get out.

And as the name states, this example also shows overlays. (Yes, I did it for you habboi, <3?)
It's a very simple entity.
Initially, I wanted to show of the advisor overlay effect, but for some reason it does not work (at least not in the same way as the others do)
So instead I used a blur overlay which... makes everything a bit blurry!

RARE Known bugs:
*Alyx is non solid to the Jeep.
I don't know if it's the same way in the original Ep2.
*Jeep gets stuck in the ground (This has never happened to me, I'll fix it ASAP)

None of these has occoured to me in any of the tests, and I've tested the map quite a few times.)
