Process::_signalProcess is destroyed first, and then Win32WindowManager::~Win32WindowManager() try to remove from deleted Signal causing a crash.
SlotSignal handle this automatically.
Example:
```
Win32WindowManager::Win32WindowManager()
{
// Register in the process list.
mOnProcessSignalSlot.setDelegate( this, &Win32WindowManager::_process );
Process::notify( mOnProcessSignalSlot, PROCESS_INPUT_ORDER );
// When Signal it's destroyed, all slots are disconected.
// When a SignalSlot it's destroyed, it's disconected from Signal.
}
```
- New InputEventManager class. It will be used by 3rd party input
devices to generate Torque 3D input events.
- Expanded the input event signal to include three new floats and a new
integer.
- Expanded the number of joystick buttons to 48.
- The input virtual map is now extendable rather than hard coded.
- The input devices types are now extendable rather than hard coded.
