Updates to freebsd 8.2, 9.0 and 9.1 tempates

Fixing up some of the existing freebsd templates, as well as taking from some amazing work already done by @jssjr in the bento world for building chef based vagrant boxes.  

Would love to get more eyes on this code, I suspect the final issues exist around virtualbox BSD support - initial provision with chef-client provisioner fails, but later ones work fine.  Still having issues with chef-solo.

Any comments, thoughts, questions, etc are more than welcome and appreciated.
