Copied Solr instance of ezfind in ezpublish/ as configuration needs to be tweaked

And I don't want to edit config files each time I update ezfind :-P
Removed index boost on "decouverte" attribute
Added eztags fields to Solr schema
Jetty running on port 8984
Removed dep on ezmbpaex and ezsi + added sqliimport and jvamazonadvertising
Added Solr logs to .gitignore
