Script for creating a bootstrap sub-theme.

In this change we have

rep -Rl bootstrap_barrio_subtheme .|xargs sed -i '' -e "s/bootstrap_barrio_subtheme/$CUSTOM_BARRIO/"

and

sed -i '' -e "s/Bootstrap Barrio Subtheme/$CUSTOM_BARRIO_NAME/" $CUSTOM_BARRIO.info.yml

however in boostrap_sass we currently have:

grep -Rl bootstrap_sass .|xargs sed -i '' -e "s/bootstrap_sass/$CUSTOM_BOOTSTRAP_SASS/"

and

sed -i '' -e "s/SASS Bootstrap Sttest2arter Kit Subtheme/$CUSTOM_BOOTSTRAP_SASS_NAME/" $CUSTOM_BOOTSTRAP_SASS.info.yml

notice the absence of the quotation marks. Why have these been removed? Doing so seems to result in the creation of files with the -e suffix
