+* Added ability to blacklist headers so that they are not shown in the request or response log. Instead the header value will be replaced with "[ BLACKLISTED ]". You can enable this per header basis using the LogConfig:
+
+    given().config(config().logConfig(logConfig().blacklistHeader("Accept"))). ..
+
+  The response log will the print:
+
+  Request method:	GET
+  Request URI:    http://localhost:8080/something
+  Proxy:          <none>
+  Request params: <none>
+  Query params:   <none>
+  Form params:    <none>
+  Path params:    <none>
+  Headers:        Accept=[ BLACKLISTED ]
+  Cookies:        <none>
+  Multiparts:     <none>
+  Body:           <none>
