Saves the game state to a save slot.

A string giving the name of a save slot. Despite the variable name,
this corresponds only loosely to filenames.
`extra_info`
An additional string that should be saved to the save file. Usually,
this is the value of :var:`save_name`.
:func:`renpy.take_screenshot` should be called before this function.
