create lang subdirs in Wnn-data package, as it's impossible
to know when to dirrm them otherwise (main package or dict ?)
Remove chinese docs from the korean package.
Let that be somewhat configurable.
Fix all documentation to refer to the right location for dictionaries.
Fix the install-script so that it can take care of all three languages at
once.
Let un-installation instructions be more helpful, explaining about usr
data.
