sin-ack 1d2bde2403 Meta: Add new-project.sh :^)
This script will instantiate a HackStudio template into a project on the
host. It currently supports all templates used by HackStudio.

To avoid having to maintain compatibility between other shells and the
Serenity shell in the postcreate scripts, we build the Serenity shell
with Lagom and use that to run the script.
