This is the first iteration of Cargo Deck MFD. It is a nod to Kulch for his Univercal Cargo Deck and Payload manager. This
MFD provides similar capabilities but in an MFD form factor.

- attach cargos/stages to each other using on screen interface
- children vessel thrust is modeled and projected onto the parent
- children vessel propellant use/mass loss is modeled and reflected in parent dry mass
- press shift + Numpad +/- to fire or cut off all children's main engines with "booster" in their name simultaneously
