Using a local __choice like in map to avoid unnecessary inconstantness
This is same-behavior, but I would be in favor of reseeding only at the beginning of the day/night instead of every time the summon menu is opened (next commit)
big work
what was reliable before is now not, in recent versions of renpy, which is why we added that new config (which I put in say.rpy, but it can be moved somewhere else)
Also fixes the game_menu's title position, incidentally
some changes are incompatible with my diary and achievement branches, respectively, they will need to be merged with a bit of manual care
technically not as correct, but works all the same and is relatively faster (but it will be replaced with better actions in the future anyway)
the pickle lock, if any, for removing them in the future, becomes easier to solve
turn the show into a call screen
replace all return actions with specific local actions (WIP, more changes to come)
make the global variables at least dynamic
make the mode parameter a parameter of the label (so, a dynamic variable too, as a result)
replace the bigger actions with local labels
tweak text entries, comparisons, iterations... details
in addition to benigh simplification, this actually fixes a bug : setting pos and align in the same line is a bug, it's always been unspecified, you should have been setting *anchor* instead. xycenter does that now.
