Fully implement HAL specification for Links.

[douglassparker]

See https://tools.ietf.org/html/draft-kelly-json-hal-08#section-5 for a list of the HAL Link, paraphrased below. The implementation of Link only complies with sections 5.1 and 5.2 and does not comply with sections 5.3 - 5.8. While I understand you may have philosophical differences with the specification on the inclusion of some of these attributes, I submit that one should not claim to support a standard unless one does so faithfully.

5.1. href REQUIRED.
5.2. templated OPTIONAL.
5.3. type OPTIONAL.
Its value is a string used as a hint to indicate the media type expected when dereferencing the target resource.
5.4. deprecation OPTIONAL.
Its presence indicates that the link is to be deprecated (i.e. removed) at a future date. Its value is a URL that SHOULD provide further information about the deprecation. A client SHOULD provide some notification (for example, by logging a warning message) whenever it traverses over a link that has this property. The notification SHOULD include the deprecation property's value so that a client maintainer can easily find information about the deprecation.
5.5. name OPTIONAL.
Its value MAY be used as a secondary key for selecting Link Objects which share the same relation type.
5.6. profile OPTIONAL.
Its value is a string which is a URI that hints about the profile (as defined by [I-D.wilde-profile-link]) of the target resource.
5.7. title OPTIONAL.
Its value is a string and is intended for labeling the link with a human-readable identifier (as defined by [RFC5988]).
5.8. hreflang OPTIONAL.
Its value is a string and is intended for indicating the language of the target resource (as defined by [RFC5988]).

Please clarify what is missing in light of #567.

Apparently, I have an older version that does not have this change. This is a duplicate of 567. I will close. Thank you for quick response.

We're close to making a 0.24 release, which should include this. Until then, if you use 0.24.0.BUILD-SNAPSHOT, you'll have access to this.
