This adds the command 'source' that prevents the final call to exit
by just returning successfully (i.e. return 0), so that other scripts
(possibly with set -e) may source this script and thus import all our
variables and functions. This makes the logic for finding important
factorio files and all functions defined in this script easily reusable.
By calling exit, other scripts using source to import this script
would be terminated.
This can be seen when running the following snippet
(which will never print "post-source with other arg"):
#!/usr/bin/env bash
set -e
echo "pre-source with source arg"
source factorio source
echo "post-source with source arg"
echo "$CMDOUT"
echo "pre-source with other arg"
source factorio version
echo "post-source with other arg"
echo "$CMDOUT"
