Drop Clojure 1.3.0 support for CongoMongo 0.5.0

Switch :use/:only over to :require/:refer; drop 1.3 from test matrix;
use reduce-kv instead of plain reduce where possible (only one place?).

 --------------
+Version 0.5.0 - Jun 6th, 2016
+
+* DROP SUPPORT FOR CLOJURE 1.3.0!
+* Add Clojure 1.9.0 compatibility (handling of seqable? in coerce namespace) - issue #147
+* Clojure is now a "provided" dependency and should no longer appear as a transitive dependency in projects that use CongoMongo, making it easier to get rid of conflicts! _Potentially a breaking change if a project depended on CongoMongo but did not have an explicit dependency on Clojure itself._
+
 Version 0.4.8 - Feb 25th, 2016
 
 * Update clojure.data.json to 0.2.6
