boxen env and reenable encryption
No hard drive encryption

Some users may not want to encrypt their hard drive, so make
sure they know the option exists to not have to encrypt their
hard drive.
Minor grammatical edit

I think in this case "bootstrap" is already a verb.

Fix typo: 1.0.5 -> 1.1.0

adds source folder for librarian-puppet git source cache
Use the boxen-git-credential for all repositories clones.

This is required since puppet run all the comands as root and the
credential config is only present on the user land.

The lack of this configuration is making clones using https to not
work since the credential is not present for the root.
