Patches from Tony Peden to separate property XML I/O operations into a separate header file. This change will help integrate properties into JSBSim. Also, I (David Megginson) removed most of the SimGear include statements from globals.hxx, reducing the amount of recompilation every time SimGear changes. This required making minor changes to a lot of files that were depending on the side-effects of the inclusions in globals.hxx.

#include <simgear/misc/commands.hxx>
General cleanups to cut cross-dependencies and speed up compilation. Added two new properties: /environment/temperature-sea-level-degc /environment/pressure-sea-level-inhg These are now supported in FGEnvironment as well, though they always have the same value for now. They need to be hooked up to the FDMs.

#include "globals.hxx"
Removed dependency on viewmgr.hxx from globals.hxx, so that changes to the viewer code do not require most of FlightGear to be rebuilt. Added some now-required includes to environment.cxx.

The FlightGear patches add new saveInitialState and restoreInitialState methods to FGGlobals, as well as the two-stage commit described above for loading saved files. fgInit now takes a snapshot of the initial state before handing off to the main loop, and the GUI reInit function restores that state explicitly before calling fgReInit. The FlightGear patches also modify fg_props.hxx to add optional useDefault arguments to all of the fgTie functions -- that lets you choose whether you want to pick up any default value in the property tree when you tie the property (the default is true).

FGGlobals::FGGlobals() :
Major overhaul: - changed FGSubsystem::update(int) to FGSubsystem::update(delta_time_sec); the argument is now delta time in seconds rather than milliseconds - added FGSubsystem::suspend(), FGSubsystem::suspend(bool), FGSubsystem::resume(), and FGSubsystem::is_suspended(), all with default implementations; is_suspended takes account of the master freeze as well as the subsystem's individual suspended state - the FDMs now use the delta time argument the same as the rest of FlightGear; formerly, main.cxx made a special case and passed a multiloop argument - FDMs now calculate multiloop internally instead of relying on main.cxx There are probably some problems -- I've done basic testing with the major FDMs and subsystems, but we'll probably need a few weeks to sniff out bugs.

Added fullscreen to globals, and fixed compile bug for 3DFX cards.
