DATAREST-93 - Fixed formatting in Spring Data REST.

Added formatter to be used within Eclipse going forward.
DATAREST-93 - Further fixes in repository mappings.

Simplified new RepositoryMappings infrastructure. Integrated EvoInflectionRelProvider to build collection resource rels. Bumped version number to 2.0 as we're going to break backwards compatibility with the next release to straighten out the rel construction and mapping.
