Added FGEnvironmentMgr to provide information on the environment in different locations, and hitched it into FGGlobals. FGEnvironmentMgr has taken over as the subsystem, while FGEnvironment is simple the information that it returns. I've removed current_environment completely -- everything now uses properties or goes through FGGlobals. FGGlobals itself has a couple of useful methods: const FGEnvironment * get_environment (); const FGEnvironment * get_environment (double lat, double lon, double alt); The first one returns the environment data for the plane's current position, while the second returns the environment data for any arbitrary location. Currently, they both return the same information, but that will change soon.

Added an interface for an environment controller, together with a default implementation that uses user-supplied params. Currently, the only parameters are /environment/params/base-wind-speed-kt /environment/params/gust-wind-speed-kt but others will show up soon (i.e. sheer, variable direction, variable visibility, etc.). To activate these properties, you have to configure --with-new-environment. The gusting function is simplistic and needs to be replaced with something better, though it doesn't feel too far off.

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.

Environment manager overhaul -- return a copy of an FGEnvironment object rather than a pointer. FGEnvironment now has the beginning of an atmospheric model, and will recalculate temperature (not pressure or density, yet) based on elevation. FGEnvironment has a copy constructor.
