Change .gitignore temporarily to get rid of all the files
Fix .gitignore
Add missing default zone files
Bind module overhaul

- Make default zones into a template for chrooting
- Remove params class and use class parameters and hiera only
- Normalize a few things (quotes, undefs, etc. not done)
- Write script to create device files for chroot
- Edit default bind config file to support chroot
- Make chroot actually work
- Add nochroot_ paths to everything because configs are expected to use them
- Make forwarders react correctly (possible side-effect of cleanup)
