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
I chose not to add them directly in the screen, to keep it readable
but even though they're still global variables, now they are dynamic and cleaned as soon as we exit the menu
- don't use a reserved name (starting with an underscore)
- use a file-local mangled name (starting with two underscores
- use renpy.dynamx to cleanup the variable automatically
