apachesolr 6.x-1.0-rc5

This release contains several important bug fixes - in particular without the follow-up patch at #630798: Implement cache_apachesolr table, sites may experience significant performance issues due to an extra metadata request being made for every MLT or search request.

Also, the Drupal 7 language-neutral code was change from 'zxx' to 'und', and this module changed to follow suit - if you are using the language facet block with language-neutral content, you may want to reindex to get consistent codes in your index.
