Cost for cargo bays on vehicles is incorrect

[assaultdoor]

I've noticed the following issues with cargo bay costs for combat and support vehicles using MML 0.47.9 on OS X:

1. All cargo bays on combat vehicles allocated through the Transport section of the Structure/Armor tab are free. Per TM p. 293, only basic cargo, cargo containers, and infantry compartments should be free.
2. Liquid cargo on support vehicles costs 100 c-bills + 100 c-bills/ton when it should cost just 100 c-bills/ton
3. Refrigerated cargo on support vehicles costs 200 c-bills + 200 c-bills/ton when it should just cost 200 c-bills/ton
4. Insulated cargo costs 250 + 250/ton when it should just be 250/ton

Updated because I forgot that cargo bay doors are expensive.

Update 2: I think this might be a floating point issue. When I create a vehicle with one ton of liquid cargo (a transport capacity of 0.91 tons), the file saves with the line "liquidcargobay:0.9100000000000001:0:1". If I manually edit the file to trim that down to 0.91 tons and then re-load the vehicle, the bay has the correct cost.
