Introduce support for media type application/vnd.collection+json. Collection+JSON doesn't allow metadata at the top, so paging data can't be covered, however, everything else fits.
Also moved a little bit more into Affordance and SpringMvcAffordance to avoid using Spring MVC annotations directly in a given mediatype's AffordanceModel.
Refactored bits of HAL-FORMS to reuse the new PropertyUtils, ensuring Jackson ignore annotations are taken into consideration. Also added MockMVC tests to show HAL-FORMS and Collection+JSON working together, against the same controller.
According to the ALPS spec, it's "descriptor" not "descriptors", despite it depicting an array of potentially multiple values. Also fixed the ordering to match as closely as possible all the samples shown in the spec.

Side effect of upgrading Jackson appears to be arbitrary change in order of property serialization. This commit forces the order to match the spec and fixes the related test cases.
Moved AffordanceModelFactory into core package as it's SPI. Switched to Spring Factories lookup of implementation classes so that we avoid a package dependency between the MVC package and the media type specific packages. Removed reference to MediaType from AffordanceModelFactory to AffordanceModel so that a factory can even provide models for different MediaTypes (i.e. different flavors of the same one, e.g. HAL Forms for JSON and XML). Also removed addAffordanceModel(…) from Affordance to not force the implementations into mutability. Made most of the affordance building API types package protected. HalFormsAffordanceModel now uses MethodParameters abstraction to simplify model parsing code.
Tweaked HAL forms model to work with factory methods for required properties and wither methods to add optional properties. Tweaked and inlined mixin types in Jackson module for HAL forms.
Slight API polishing on Link to make sure Affordance collecting methods are not named with….
Tweaked Lombok setup to use all caps for logger constants. Removed deprecation warnings in Jackson2HalModule.
* Introduces new Affordances API to build links related to each other to serve other mediatypes
* Introduces HAL-FORMS, which uses affordances to automatically generate HTML form data based on Spring MVC annotations.

Since `ResourceSupport` has direct access to the list of links, no need to build up an intermedia `List` and then filter on it. Simply filter on the internal list of links. Also did some minor polishing.
Moved RenderSingleLinks enum into HalConfiguration. Simplified HalConfiguration setup by moving the default into the class. The lookup of a user-provided HalConfiguration is now handled on the bean name level to avoid premature initialization of a potentially defined bean. Formatting.

We now expose HalConfiguration to be defined as Spring bean in user configuration to control certain aspects of the HAL rendering. Initially we allow to control whether links shall always be rendered as collection. If no user-provided bean is available, we register a default instance.
