Adding more textproc/aspell-* packages

[rodent%NetBSD.org@localhost]

Greetings,

After the freeze, I would like to add the remaining dictionaries for Aspell
0.60 listed here:

ftp://ftp.gnu.org/gnu/aspell/dict/0index.html#0.60

However, I would like to rename the ones we have by language code as listed on
the site also. The reasons for this are:

1) Shorter package name;
2) Be consistent with kde3-l18n-*, kde4-l10n-*, hunspell-*, lang-* PKG_OPTIONS;
3) Simplify modifications to PKGNAME in their Makefiles;
4) Accordance with international language naming standards;

TIA
