MimeTypes detector detects text/plain content type of a PPT file
----------------------------------------------------------------

                 Key: TIKA-689
                 URL: https://issues.apache.org/jira/browse/TIKA-689
             Project: Tika
          Issue Type: Bug
          Components: mime
    Affects Versions: 0.9, 1.0
            Reporter: Joseph Vychtrle


If I create a PPT file like this 
{code}
import org.apache.poi.hslf.model.Slide;
import org.apache.poi.hslf.model.TextBox;
import org.apache.poi.hslf.usermodel.RichTextRun;
import org.apache.poi.hslf.usermodel.SlideShow;

	private void createPPTDocument(String from, File file) throws Exception {

	      SlideShow ppt = new SlideShow();
	      Slide slide = ppt.createSlide();
	      TextBox shape = new TextBox();
	      RichTextRun rt = shape.getTextRun().getRichTextRuns()[0];
	      shape.setText(from);
	      rt.setFontSize(7);
	      slide.addShape(shape);
	      shape.setAnchor(new java.awt.Rectangle(50, 50, 500, 300));  //position of the text
box in the slide
	      slide.addShape(shape);
	      FileOutputStream out = new FileOutputStream(file);
	      ppt.write(out);
	      out.close();
	}
{code}

And then :
{code}
MediaType mediaType = MediaType.parse(tika.detect(is));
{code}

It results in text/plain, MimeTypes detector used, the magic header simply doesn't match and
then it falls back to text/plain.
