Release 3.9.4

Carrot2 Project......
Carrot2: open source framework for building search clustering engines
The 3.9.4 release fixes the following issues.
Credentials passing for HTTP BASIC or DIGEST authorization is now supported.

URLResourceWithParams and RemoteXmlSimpleSearchEngineBase now accept properties for basic http authorization to proceed. The properties can be passed either dynamically (via controller attributes) or via system properties http.auth.username and http.auth.username.

Truncate long documents in the webapp.

The webapp now has an option to truncate long document content (QueryWordHighlighter.maxContentLength).

Updated foamtree visualization to version 3.2.3.

FoamTree visualization has been updated to the new shiny version.

Clustering by majority language.

New attributes are available in MultilingualClusteringDescriptor. It is now possible to cluster using the language prevailing in the set of input documents. This is particularly useful if language detection is a heuristic that makes occasional mistakes (then majority-voting will pick the language for clustering).
