Split language-specific files

[wjt]

I noticed today that this app is 33.9 MB (or 38 MB, depending on who you ask) installed and was curious why.

Digging into share/vim/vim81:

share/vim/vim81/lang is a funny mix of localized menu_$LANG.vim files, and standard gettext-ish per-locale directories in an unusual path. It should be possible to ship share/vim/vim81/lang in a Locale extension that can be partially-installed in the normal way.

There are also locale-specific files in share/vim/vim81/tutor and share/vim/vim81/spell, if one could bring oneself to arrange the necessary symlink farms
