Adds scanning animation after splash screen

I've now got it all in sync. The length of the animation can be changed with a single variable, so if you want to watch it in slow motion, simply increase "rtime".

I've got it set up so either running the animation in its entirety or pressing any key (other than START) will take you to the character select screen, while START takes you back to the main menu. Pressing START while on the character select screen also takes you back to the main main (rather than replaying the animation).

However, there's still an error. If you view the animation again, it'll pick up where it left off rather than restarting. I don't know how to fix this.
