Add more info to JS objects

Adds a "direction" field to JS structure objects, which represents the direction the structure is facing (from 0 to 3, in 90 degree increments).
Adds an "isFlying" field to JS droid objects, which is true if the droid (VTOL or Transport) is currently in the air, false otherwise.
