[tor-commits] [nyx/master] Move panels into their own module



commit fa3a3f0eb11eec7d5af69148f1fc1deff0f6d9bd
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>
Date:   Tue Mar 8 09:40:12 2016 -0800

    Move panels into their own module
    
    Now that we're done overhauling the panels lets move them into their own
    module. They've all had the same naming convention ('foo_panel.py') so this
    just makes the grouping more explicit.
