KISS: RemoveType is a simpler fix for .tr; explain .da files; order our

LanguagePriority by a first-order comparison and drop negligable translations
from our ordered priority preference list entirely.

A better comparison would be total number of documents in-sync, or some
convoluted weight ordering each document by which are more in sync than
others. Leaving that puzzle to an interested hacker.
