Updating compatibility matrix with SCOSB and OSBAPI versions
Updating default buildpack to empty String. Nulls are not allowed by operations and the only way to enable autodiscovery is by passing and empty list, passing an empty String will trigget that behaviour. Updating tests to document the default buildpack
Some trade-offs:
The `ParametersTransformer` interface takes all the backing apps because otherwise we wouldn't allow users to config properties for each one of them.
I went for the simple solution of adding the `Bean` instead of going all the way through strategy matched via config.
Closes#22
Use a simple spring properties file for configuration
Support a single application per request
Implement component test using contract stubs for the CF API
Example application with configurable catalog
Exclude transitive dependency on JUnit 4.
Closes#4
