Update JacksonAutoConfiguration with nicer defaults

The ObjectMapper instance is now created thanks to Jackson2ObjectMapperBuilder
in order to use the same nice default configuration than Spring Framework
4.1.1.

Customized properties are:
 - MapperFeature.DEFAULT_VIEW_INCLUSION set to false
 - DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES set to false

Fixes gh-1237
