Do not remove Linux headers during minimize step

Removing Linux headers seems to be causing issues around guest tool
builds in recent updates to Ubuntu 14.04. Leaving the headers around
seems to address any issues and they don't make the compressed image
much bigger.
Pushed v1.0.2 build to VagrantCloud under https://vagrantcloud.com/box-cutter
Make headless a command line parameter and Makefile option (HEADLESS)
Values can be "true" or "false".  Default is false.
Adding "make validate" target which runs "packer validate" on all templates.
Add option to peform kernel upgrade - AUTO_UPGRADE="true" (default is "false")
Removing extra apt-get call.
Embedding the insecure Vagrant private key directly into the vagrant.sh script.

This avoids the somewhat heavy-handed approach of mounting a "floppy" which isn't universally available across other OS instances.
