Comment: | Reorganize testing framework:
* move tests into new test/ source dir
* add nice runnable unit tests for core components
* retested most of the core components
Other:
* fixed minor bugs with analysis and such
* add cleaned titles to prefix indexes
* only essentials in wordnet aliases
* patch lucene with lucene-1337, we'll see how it goes once NFS is up again on WMF servers
* kstem-based plural->singular conversion |
