Fixed up more loadstate logic. We had a slight logic error this whole time that wasn't a problem until now. Checking to see if a state is a future event, we assumed frame counter of the state matched the length of the movie. Now that movie finished is a mode, that is no longer true. Fixed that, and fixed the input display updating at the end of a load state to always look at the state input rather than the statemovie last record. This fixes proper behavior of saving and loading states during movie finished mode as per the "Laws of TAS": http://tasvideos.org/Adelikat/LawsOfTAS.html
