Support for $ref

A the moment jsonschema2pojo doesn't support "$ref" style syntax for referencing other schemas (see http://tools.ietf.org/html/draft-zyp-json-schema-03#section-5.28).

Some factors to consider:

• We need to make sure we have support for relative URIs.
• Where a second refs exist to an already referenced schema, we should be reusing the same java type IMO
• The ref mechanism is still under discussion and may change in the next draft (see http://groups.google.com/group/json-schema).

One important change here is to move away from using "id" to optionally specify Java type for code generation. The unique id/uri of a schema will be important when resolving refs, Having re-read the id part of the spec[1], it's clearer to me now what the intention of id is

The good news is that the core schema[2] allows additional properties for schemas themselves - so any additional meta-data can be attached to a schema.

The first step here is going to be introducing a new optional additional schema property 'javaType' that will be used to specify/override the target Java type name.
