GetScheduleDuration / GetTimeSinceStart Function Fixes

GetScheduleDuration and GetTimeSinceStart schedule functions no longer work!!
These are two simple functions i wrote in 2005 which were added to the SDK.

Somewhere along the lines, my extra code added to simmanager.cc disappeared

in simManager.cc around line 79 in PostEvent

event->time = time;
[b]   event->startTime=gCurrentTime; //Ramen Hack[/b]
   event->destObject = destObject;

This one line needs to be added in giving start time a real number to use. Without it, starttime is never given a value, and you get an erroneous value.

I've added this back into my code and confirmed it works.
