Apparently there was already a function for reseting the frame wait,
used commonly after loading files. So we don't have to use the hacky
method of making the game wait for X number of frames anymore.
The game would try to catch up in frames when a window prompt was
opened, so if the window was open for 140 frames the game would process
the next 140 frames instantly after the game was closed. To fix this, I
have the window prompt time how long it's opened and then I tell the
game to sleep for however many frames it was opened for.
Credits message works but does not yet have all the desired features,
will finish up later.
