Fix issue Felix-813.
XML-Schemas are now embedded in the manipulator. The manipulator tries to use those files to validate the metadata.xml file. If a schema cannot be loaded "internally", the regular downloading process continue.

The internal resolution of schema can also be skipped by setting the ignoreEmbeddedSchemas parameter:
Ant: ignoreEmbeddedSchemas="true" attribute in the iPOJO task
Maven: <ignoreEmbeddedSchemas>true</ignoreEmbeddedSchemas> in the iPOJO plugin configuration
