Update runtime so process is defined as variable

Define `process = "{game_name}"` in startup instead of calling
`process()` at the top of the auto splitter.

The auto splitter script will now keep running if the game is closed and
will try and find the new game process before continuing, instead of
running the entire script again from the start.
