Update freebsd versions

[chpatton013]

NOTE: This PR is currently based off of #43, and will be rebased to remove that commit once it merges.

Update the FreeBSD 11.1 template to 11.4 and add templates for 12.2 and 13.0.

I tested by building all three of these images using the virtualbox-iso builder and booting into each of them, but since there was nothing exotic in the templates I didn't bother building with vmware or parallels.
