Concept for wet workshop

[LouisB3]

Inspired by Space Station Enterprise from Boldly Going.

Ideal conversion process:

1. Eliminate propellant storage
2. Consume some resource such as MaterialKits to represent adding equipment
3. Add functionality:
   3a. crew capacity
   3b. life support modules (KerbalHealth)
   3c. (optional) science lab modules
   3d. life support resource storage? (e.g. Snacks)

Known relevant mods:

• BDB has a plugin for handling wetlabs. Can do 1, 3a, 3c. Not 2 or 3b
• WBI has a plugin for handling wet workshops. Unknown functionality, probably heavily integrated with other WBI gameplay
• B9PartSwitch is ubiquitous and can handle 1, 3d, and possibly 3b or 3c, not 2 or 3a.
• SSPXr has a deployment animation plugin that can handle 2 and 3a, probably not the rest.

Possible solution involves using a combination of B9PartSwitch and SSPXr to handle different parts of the functionality.

Partially works. ModuleDeployableHabitat from SSPXr doesn't work if the part doesn't have an animation, which fuel tanks won't. Fix TBD.

Also to be investigated: can moduleActive = false in B9PS subtypes be used to require venting fuel before deploying (kitting out) the habitat? If so (and the above fix) then this will be a really neat solution.
