ConceptNet 4.0rc2 released

[Rob Speer]

ConceptNet 4.0rc2 has been released. You can get it from Launchpad
(http://launchpad.net/conceptnet) or with "easy_install -U
conceptnet".

You can use this version even with a 4.0rc1 database, so please help
test it and report bugs!

Code changes:

* Made almost all of `csc.nl` work independently from the database,
and only import the database settings if it absolutely needs to. This
lets `csc.nl` work even when a different Django database is loaded.
* Added support for Hungarian (using PyStemmer's new Hungarian
support), in `csc.nl.hu`.
* Added experimental support for Japanese in `csc.nl.ja`, thanks to
Tyson Roberts. This uses MeCab and CaboCha to tokenize and lemmatize
Japanese text. This replaces the previous trivial `csc.nl.ja` module.
Japanese concepts have not yet been updated, however.
* `csc.nl.euro` now contains methods for extracting relevant words and
phrases from free text.

Database changes:

* Imported the Traditional Chinese ConceptNet (thanks to Yen-Ling Kuo).
* Corrected some common types of parsing errors, such as parsing "[X]
is [for Y]" instead of "[X] is for [Y]". Some of these were introduced
by Verbosity.
* Updated English concepts that disagreed with the lemmatizer.

The database schema has not changed, so the 4.0rc1 database should still work.
