We need to consolidate and update the Eclipse ESB creation wizards to cover ESB artifacts that users will want to create.

Specifically, we should define an extension point for example content that will allow users to add templatized ESB file content to either new or existing Eclipse projects. This example content will be derived from the JBESB "quick starts" and should be versioned so changes across JBESB run time versions can be accommodated by the wizards.

As part of this work we will need to determine if an ESB project type (and associated project nature) makes sense, and whether JBESB files can be built as part of other project types.
