Fixed towntun1

Added 8 new ENTERABLE/USABLE signal boxes to /buildings/acc.

PLEASE NOTE that signal boxes 3a and 3c have a ladder feature that doesn't currently operate. It is for looks only. I can try and make this usable in the future but no promises

Added numerous road pieces, buildings, map props.

Added base1 to /vehicles/boats/, just as a random deck size for people to use
Added destroyer to /vehicles/boats/, a random simple destroyer vaguely based on what I think is an Arleigh Burke class of destroyers. Kinda. It's a boat. Has two spots for turrets (a big and a small one) and a space for a helicopter to land on. If it's small.

Added cybercar3 and cybercar4, just a basic flatcar to carry 1 or 2 containers respectively
