Add getter for related view on ApachesolrViewsSolrBaseQuery

In my current project we have build a module to add custom filters and export functionality in a Solr based views. After some time we have decided to add support to a custom entity and create a custom Solr dashboard/export for this entity too.

The problem is that we used hook_apachesolr_query_alter to handle our custom filters and in this hook there is no information about which views the ApachesolrViewsSolrBaseQuery object is related.

In order to be able to check the view name and display, I've updated the ApachesolrViewsSolrBaseQuery class to include the view object and provide a getter callback so we can get any information we want from the query related view.

$view = $query->getView();
