Wardrobe fix

Fixes #4447

- Added a parent call to each wardrobe subtypes New() proc.
Wardrobes weren't calling obj/structure/closet/New(), so weren't adding items in the same location to their contents when first created.

- Removed wardrobe/New() proc.
So all subtypes don't inherit an extra set of blue uniforms and brown shoes. Only one wardrobe on the map is of this type, and it's on the derelict, so didn't think it was worth making a map change.
Mech fab upgrade fix

Nano manipulators were not lowering build time at all.
Stock and Pico manipulaors were lowering build time by 6%.

This fixes that. Now: Stock = standard build time, Nano = 6% faster, Pico = 12% faster.
