boolean org.sleuthkit.autopsy.contentviewers.MediaPlayerPanel.isSupported ( AbstractFile file )

Although it seems too restrictive, requiring both a supported extension and a supported MIME type prevents two undesirable behaviors:

1) Until AUT-1766 and AUT-1801 are fixed, we incorrectly identify all iff files as audio/aiff. This means that if this panel went with the looser 'mime type OR extension' criteria we use for images, then this panel would attempt (and fail) to display all iff files, even non audio ones.

2) The looser criteria means we are less confident about the files we are potentialy sending to GStreamer on 32bit jvms. We are less comfortable with the error handling for GStreamer, and don't want to send it files which might cause it trouble.
