MNT-16181 transformations for application/dita+xml

Browse Source 
- StringExtractor is now able to extract text so searching is now working, which was the main reason for this Customer issue.
   - PdfBox.TextToPdf is now able to transform .dita fiels to .pdf. As a result it is also possible to preview the files (although the xml tags are visible) and
     to generate .png thumbnails using the complex.Text.Image transformer (which has an intermediate .pdf stage).
   - As expected TikaAuto (or our patched 1.6 version) does not know about the DITA mimetype application/dita+xml so is not claiming to transform this type even
     though it is just an XML file.
