Added static port system and a new altimeter model connected to it. The static port uses the /systems/static/ property subtree, and the altimeter uses the /instrumentation/altimeter/ property subtree.

This is step "1" of probably "many" in the process of separating out the scene management code and organizing it within simgear. My strategy is to identify the code I want to move, and break it's direct flightgear dependencies. Then it will be free to move over into the simgear package. - Moved some property specific code into simgear/props/ - Split out the condition code from fgfs/src/Main/fg_props and put it in it's own source file in simgear/props/ - Created a scene subdirectory for scenery, model, and material property related code. - Moved location.[ch]xx into simgear/scene/model/ - The location and condition code had dependencies on flightgear's global state (all the globals-> stuff, the flightgear property tree, etc.) SimGear code can't depend on it so that data has to be passed as parameters to the functions/methods/constructors. - This need to pass data as function parameters had a dramatic cascading effect throughout the FlightGear code.
