DATAREST-229 - RepositoryEntityLinks now exposes templated links.

If the resource exposed for a domain or repository type is considered a paging resource we now return a templated URI. Introduced ResourceMapping.isPagingResource() to allow clients to find out about whether the resource is actually capable of pagination. Adapted implementations to inspect the findAll(…) method as well as the search methods for a Pageable parameter.

Tweaked pom.xml to create correct classpaths if the IDE uses direct workspace project references.
DATAREST-31 - Improved link rendering for search resources.

If the search resource is capable of paging we now augment the link with pagination template variables.
