-- rotate_statusbar.lua
--[[
This replacement for cfg_statusbar.lua will rotate between
statusbars at a user defined interval. This is handy for
status information you are not interested in all the time such
as what song you are playing or wireless strength and so on.
Usage:
1) Back-up the existing ~/.ion3/cfg_statusbar.lua (if present).
Rename this file called rotate_statusbar.lua to ~/.ion3/cfg_statusbar.lua.
2) Make changes to rotate_statusbar.settings.allbars (see below "USER DEFINED").
Each table represents a new status bar that will be shown.
3) For further changes, look into save_statusbar.lua, which will
be created by this script). Also notice init_settings and configurations.
4) Now restart ion3 (hit 'F12' then type 'session/restart')
This is heavily based on ctrl_statusbar.lua by Sadrul Habib Chowdhury.

TODO:
All meters (whether visible or not) run in the background. It would be
nice to only run the visible meters to avoid wasting CPU.
- Can I access that functionality from here?
