use a custom query to create a more informative languoid.csv

[xflr6]

• fix clld/glottolog#138

to test by creating only this download:

import sys

from clld.scripts.util import parsed_args
from clld.interfaces import IDownload

sys.argv = ['spam', 'development.ini']

args = parsed_args(bootstrap=True, description='spam')

csv = dict(args.env['registry'].getUtilitiesFor(IDownload))['languoid.csv']

csv.create(args.env['request'])

Not sure if we really want the newick column (at least Libreoffice seems to throw an error related to the maximal cell size).

Still something wrong with the iso639-3 column: let me take another look

[xflr6]

Fixed.
