feat: player runtime for goodluke and SaintlyCorruption

Text fields (`input`) with InputValue classes games can extend, continue/break in screen loops, Confirm,
CaptureFocus/ClearFocus/InvertSelected, generator functions and iter/next, starred tuple items,
renpy.file and json over data files loaded before the game starts, renpy.Container and
register_sl_displayable, DiamondBox layout, ConditionSwitch/DynamicImage/Animation, renpy.show(what=...),
callable transforms (`store.move_in(0.3)`), call_in_new_context as a call, im.matrix/im.Image/
MatrixColor, colorsys, fnmatch, FontGroup, persistent._clear and small renpy helpers.
