lemonbar support script
This script was from Peter Hessler via Pamela Mosiejczuk. I believe he got it from elsewhere.
I'm slowly customizing it to work for me and to be less opaque to read.
Current advantages over other versions I've seen:
- Factored out the magic color strings
- Factored out the network interfaces into a variable for one easy change
- Added support for a trunk interface and detection of wired interface usage
- Battery status is split into four color categories for each 25% of battery
- Touching ~/.newbar will get the script to re-exec itself. Useful for development.
