make get_advanced_search_facets method work with latest version of blacklight. check for default qt in new config location, and pass qt to find method as first parameter to conform to other calls to that method (though it only uses args[1] right now)
Merge whumph's fix for BL 4.x, issue #10.

Merge branch 'master' of https://github.com/whumph/blacklight_advanced_search
remove ref to blacklight_config.default_qt

Doesn't exist anymore. Thanks @jcoyne. See #10
