Crawler 2.0

[unknao]

The Crawler as it is right now is a pretty terrible vehicle to put it lightly, it is unwieldy, not very good at crawling and not very fun to drive around. I have rewritten most of the logic for movement to make it much more controllable and less jittery.

Changes:

• Renamed the class from "Crawler" to "prop_vehicle_crawler" to not have such a conflicting name.
• Removed all other entities aside from the main crawler.
• Recompiled the bike model to have attachment points to remove the need for trail SENTs.
• Recompiled the wheel to not have such retarded angles and moved all of its logic to the client (no more wobbly jittery wheel).
• Gutted pretty much all of the hover code and replaced it with something that's MUCH better (it can drive on walls and drive at a not snails pace speed now).
• Added a steering wheel animation using the bone that was already there.
• Energy colors now change for people who join after they've been set.
• The gizmo now points at world angles properly.
