search_api_attachments 8.x-1.0-beta1

This is D8 beta1 release of search_api_attachments module.

This module depends on search_api that is usable but not yet stable, and so, it is not recommended to use this version in production.

Especially, note that there is no data update path for this module's configuration!

This release fixes only some bugs and add one feature (the feature is that all solr backends that implement SolrBackendInterface can now be choosed for extraction ).
