There were some issues with how results were being displayed in searches versus entity lists. This code changes the way all results are displayed by offereing several options for output. The default is to inline the entity in the response and page the results (defaults to 20). If the UA sends an `Accept` header of `application/x-spring-data-compact+json` or `text/uri-list`, however, SD REST will output a compact list of only links and will not inline the entities.
The method of output was completely rewritten to use HttpMessageConverters exclusively. Views and the subsequent ContentNegotiatingViewResolver machinery have been elimintated. This should make it easier to embed inside an existing Spring MVC application. This is also easily extendable so the user can plug in their own set of HttpMessageConverters for any output format they like (JAXB, Atom/XML, etc...).
Also added was JSONPE support. By setting the `jsonpParamName` property on the `RepositoryRestConfiguration` customization class, the user can change the default JSONP param name of `callback`. There's also a `jsonpOnErrParamName` property on that configuration (defaults to `null`) that will allow you to capture errors using JSONP. Normally this would not be possible using script element injection, but the REST controller changes the status code to 200 and pass your javascript function the actual response code and wraps the error as the second parameter.
