TickManager.as - set BASE_FRAMERATE based on SWF framerate

[mikechambers]

Right now, it is hard coded, so if we change it in the SWF, we have to change it in the code.

We should just initialize it from the SWF.

I updated the FPS_RATE property to match the SWF : 06bd0c6

But we still need to base this off SWF framerate. Main issue right now, is that the information is needed before the stage has been initialized, so we have to change when the data is accessed. This includes changes in all classes that access the property.
