Replace spaces with tabs
Change __nat_init function name to match other functions in the switch library
Completely rewrite guest support, making vm-core logic much cleaner
Guests are now supported via the lib/vm-guest library
Each guest has a function which unifies the install/run logic in once place rather than two.
Loaders now run in the background; Not 100% ideal in some cases but better for most.
This also fixes the small tap0 issue which will now only present itself if you start a guest
with no networking
All guests need more testing with these changes but should be functional.
lib/vm-zfs wasn't checking $VM_ZFS properly, causing it to try and use ZFS when it wasn't enabled.
'vm image' commands have been completed to a basic level.
You can image a virtual machine, then provision a new one using the image.
Simplify main script and move functions into independent libraries.
Add a Makefile to install everything to the correct places.
Add an initial man page.
