Added a new metadata extractor based on POI for docx, xlsx and pptx mime types. Changed OpenOfficeMetadataExtracter so that it no longer supports these mime types. Added the new test code to ContentMinimalContextTestSuite Some tidying up of code in AbstractMetadataExtracterTest and OpenOfficeMetadataExtracter to reflect the fact that this extractor does not handle these mime types any more. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@19792 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
