port: ItemData, ItemManager, PythonNonPlayer + LoadLocaleData (batch 2 P3-a)

Verbatim 40250 GameLib ItemData/ItemManager and UserInterface
PythonNonPlayer(+Module) replace their pending stand-ins and the
nonplayer module stub. LoadLocaleData's body moves into the platform
CPythonApplication stand-in, so the select phase loads item_proto and
mob_proto; CPythonSkill is still pending, so it returns false after the
tables load. login_flow checks item 19 (Sword+9) and mob 101 (Wild Dog),
offline and live.
