Add custom icons to several apps at once.

install-app-icons.sh

#!/usr/bin/env bash

# You will need to update app names, paths to apps, and the location of the
# custom app icons. Also, each app includes a `has_copied` var, and each one
# should be 1 higher than the previous. Lastly, the conditional on line 32
# should be updated to match the value of the last `has_copied`. That will
# trigger a restart of the Dock to ensure the new icons are picked up.
#
# There is likely a MUCH smarter way to pull this off. I welcome
# recommendations and optimizations!
