New Revision: 555630

URL: http://svn.apache.org/viewvc?view=rev&rev=555630
Log:
Added two new Import wizards:
	o ImportSchemasFromOpenLdapWizard
	o ImportSchemasFromXmlWizard
Updated SchemaChecker to check the whole schema inside an Eclipse Job.
Updated XMLSchemaFileImporter to import files with multiple schema definitions.
Fixed a bug in OpenLdapSchemaFileImporter which caused the schema to be empty with no AT and no OC.

Added:
