[Won't fix] conveyor belts

[cccp_leha]

Maybe I've been under a rock, but you move faster than the conveyor belt you are standing on ("Scrolls player [direction] ([speed])" in WA).

The Sector Special conveyor belts always do that for some reason. However, the line special and ACS special conveyors work fine. Weird.

The sector types exactly match their Hexen counterparts. Since the BOOM line types offer an equivalent and correct method to scroll floors, I'm not going to change this.
