Releases for Porter-Stemmer

This release is Drupal 9 compatible. There have been minor changes to some automated tests, and some deprecated code has been rewritten, but there are no changes to the functionality.

First release for Drupal 8. The code is an object-oriented port of the Drupal 7 module. It is passing all the automated tests, which are comprehensive like the Drupal 7 tests.

Development snapshot.

Currently the same as the 7.x-1.0 release. Nothing has been changed. Yet.

Changes since the last version:
- Fix problems in excerpt matching function (issue: #850950: capitalization can cause porterstemmer_sbp_excerpt_match() to miss matches )

Uses the PECL stemming library from http://pecl.php.net/package/stem if available, for efficiency. This library functions exactly the same as the PHP implementation in the Porter Stemmer module, and is several times faster due to being compiled and integrated with PHP itself (if it is installed on your web server).

Add implementation of exerpt hook for Search by Page module, for better highlightin of stemmed keyword matches in search output. See issues:
#493270: search_excerpt() doesn't work well with stemming

The main purpose of this release is an upgrade to Version 2 of the Porter Stemmer algorithm - see issue http://drupal.org/node/511930

This release also fixes the following issues:
* Make minimum word size for stemming be 3 characters - see issue http://drupal.org/node/219335
* Make sure all function names have module prefix - see issue http://drupal.org/node/437094

Development release of the Porterstemmer module compatible with Drupal6.x

Thanks to ceejayoz for the port to Drupal6.

If this works well then I'll create a 6.x-1.0 release in a few weeks.

A 5.x compatible release of the Porter-Stemmer module. Currently includes basically no changes from the 4.7 version of the module.
