Big cleanup of Vagrant transitioning everythign to CentOS, building the basebox from definitions, and parameterizing the modules so another OS can be easily added.  Eliminated the double hosts for simplicity.
For now just have a isngle vagrantfile in the root, we can branch distros later if necessary.
Add vagrant build info to the developer docs
Vagrant tweaks.  Remove the Vagrantfile form .gitignore.
Ignore vim/emacs backup files.
Merge branch 'master' of github.com:Jazzee/Jazzee
Fix git ignore so base boxes are not commited.
