Aircraft/Generic/MPCarriers.nas: added support for always tying AI and MP carriers together.

Browse source 
We tie MP and AI carrier together if /sim/mp-carriers/latch-always is true.

This is done by setting /ai/models/carrier[]/ai-latch to the
/ai/models/multiplayer path containing the corresponding Multiplayer
information. C++ code will detect this and copy across the position and
orientation each frame.
