tile-service now uses dot notation for query parameters rather than ecnoded json. Separated layer state setting/getting functionality into separate resource class and urls.
Changed server response status to prevent caching of states get response.
Fixed default ramp type and config merge bug.
Added proper caching directive to prevent caching of layer states. Prevent caching of annotation reads as well.
Added example to QueryParamDecoder doc. Added proper logging of errors in new ConfigurableFactory methods. Removed unused method from TileResource.
Fixed javadoc style in QueryParamsDecoder.
