#202 - Prepare next development iteration.
#201 - Traverson can now take a customized RestTemplate.

Traverson now has an additional constructor taking a RestOperations instance which will be used instead of the default one. This allows more fine grained control over the HTTP request infrastructure used when performing link traversals.

Some internal polishing (moved from RestTemplate to RestOperations).

Moved to a setter based configuration for both the RestOperations and LinkDiscoverers to be used.
