Add SearchBuilder to catalog_controller and filter to catch extra commas in points_list_s

[stevenvandervalk]

Has been tested against vagrant for the comma filter. Not entirely sure how searchBuilder changes things just yet but solr is still giving a 400 error on my vagrant when submitting a bbox param to limit the spatial results. So not sure about which "GEOMETRY_FIELD" is applicable etc.

 INSERT INTO "searches" ("created_at", "query_params", "updated_at") VALUES ($1, $2, $3) RETURNING "id"  [["created_at", "2015-05-20 06:18:34.054109"], ["query_params", "--- !ruby/hash:ActionController::Parameters\nq: africa\nshowmap: 'on'\nbbox: -116.71874999999999 -88.63495099695557 150.46875 88.27655136092483\n_: '1432102680148'\ncontroller: catalog\naction: index\n"], ["updated_at", "2015-05-20 06:18:34.054109"]]
