Refactor idlist, move all global vars to local scope

- Replace list_foreach with LIST_FOREACH macro.
- Remove `game` global variable and make it local everywhere.
- Move global vars `fld`, `nxt` and `texts` into `game` struct.
- Add `static` qualifier to engine.c's specific global vars.
- Move `sfRenderWindow window` global var to local scope
