Vehicles trapping type

[strusik01]

Is your feature request related to a problem? Please describe.
Currently there is no trapping category for vehicles (artillery, carts, boats etc.) nor structures, that would allow typing their specific properties in.

Describe the solution you'd like
Adding a specific "Vehicles" category for trappings, including properties like:
Vehicle name,
Cost,
Crew,
Vehicle Enc.,
Carry Capacity,
Availability,
Motive Power,
Move,
Toughness,
Wounds,
Length (yards).

I took these out of the new Dwarf Player's Guide book. Both dwarven artillery and skycraft use those properties.

These properties shouldn't be mandatory though (in best case scenario hidden if not filled), as for example carts and boats from Up in Arms are slightly different:
Name,
Enc (probably same as Vehicle Enc),
Encumbrance limit (probably same as Vehicle Enc.),
Toughness,
Wounds,
Cover Penalty

These^ also apply to Structures, I'd see it as another category perhaps, or 2 in 1 like "Vehicles and Structures".
