The code for extracting .dwg files has been contributed to Apache tika, and the Alfresco metadata extractor deep calls into Tika to have the work done. We retain our own tests of this however.

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.
