Ensure that the Seam Project wizard opens the Seam perspective with the Web Development perspective as preferred

This task is an extension of JBDS-1554. When creating a new Seam Project, the Seam perspective is already set as the final perspective and opened by default. We also need to add the Web Development (perspective) to the "preferred" list. This can be done by updating the Seam Project wizard's "newWizard" extension point and setting the "preferredPerspectives" properties. In order to see these properties, you'll need to grab the Eclipse SDK and Eclipse Platform SDKs to be installed if they aren't already or they won't appear as options in the plugin editor.

final perspective ID = Seam perspective (already done)
preferred list = Seam perspective and Web Development perspective IDs
