Mention abio library and Tools (example aubiotrack) in the jack utilities section on jackaudio.org/applications/

Hello everyone,

I want to suggest to add the aubio tools (https://aubio.org/) to the 
utilities section on the jack applications page 
(http://www.jackaudio.org/applications/).

The tools can be used for audio labbeling. I personally use aubiotrack 
from the aubio-tools package (standard package in ubuntu) to sync music 
to lights in realtime together with QLC+ using aubiotracks midi output.

Aubio comes with jack support.

Best regards
