Move TriggerMenuXML to BASH, master branch (2020.04.16.)
Switched XMLDumperFromAthena.sh to use bash instead of zsh.
My main motivation is that in the "ATLAS Docker images" zsh is not installed. (I'm using such images for my offline software developments these days.) As we "officially" only support bash for our offline software. So I thought this would be a useful change...
