[libvoikko] Libvoikko 4.2rc1

[Harri Pitkänen]

Hi!

Finally I found time to start preparing for new release of libvoikko.
The release candidate is available here:

   https://www.puimula.org/htp/testing/libvoikko-4.2rc1.tar.gz

Significant changes since 4.1.1:

* Support for Malaga (dictionary format 2) has been removed.
* Unmaintained MSVC build system has been removed.
* Dependency on hfst-ospell has been updated from 0.4.5 to 0.5.0.
* Developer friendliness of hyphenator API has been improved:
** voikkoInsertHyphensCstr, a function to produce hyphenated words
    has been added in the core library. Previously similar functionality
    existed only in the wrapper APIs.
** Hyphenation functions for C, Java, Python and JavaScript now allow
    developer to specify the string that is used as hyphen (useful if
    you want to insert HTML soft hyphens)
* Java wrapper now requires Java 7 or later.
* Some modernization of Python wrapper module
* JavaScript port has been updated to work with latest Emscripten
   and optionally produce version that is suitable for use with Node.js.

Please test this version (especially on new OS versions) and report any
issues you may find.
