Clean up dependencies in nuxeo Manifest files

manifest files in nuxeo modules should be reviewed so that:

• every manifest with a "Require-bundle" property and that will never be deployed on eclipse like webapp-core or ui-web should have this property renamed "Nuxeo-Require".
• every other manifest without a "Nuxeo-Require" property should have its "Require-Bundle" property value duplicated into "Nuxeo-Require"
• every manifest with a "Require-Bundle" property should be checked against eclipse to see if the requirement statements are correct in this context.
