Add /iris language and /iris debugdump on both platforms

/iris language opens a locale menu and sets the language for the caller
or, for a gamemaster, the server default; /iris debugdump writes a
diagnostic report and optionally uploads it. Neither needs iris.all, so
a plain player can reach them. Every modded command now executes inside
a language audience scope, and the Bukkit dispatcher opens one around
execution, tab completion and help. Permissions, message keys and the
shipped locales follow.
