Fix various uses of $(dirname "$0") where use of $BASH_SOURCE would have been more apprporiate. For example, bash -c 'source myfile.sh' would have $0 set to bash, but $BASH_SOURCE would contain myfile.sh.

BASE_DIR="${BASH_SOURCE%/*}"
if [[ ! -d "$BASE_DIR" ]]; then BASE_DIR="$PWD"; fi
source "$BASE_DIR/foo.sh"
source "$BASE_DIR/bar.sh"
