Some little improvements on Audio & MIDI recorder:
- Added track duration to file lists on UI & webconf. Both audio & MIDI files.
- On UI, now wav, ogg and mp3 files are shown, but when several formats are detected for the same filename, only the most important one is shown, being the precedence order: wav, ogg, mp3. This allows, for instance, to delete wav files after compressing to ogg from webconf. Beware that deleting from UI will delete all formats for the selected filename!!
