Remove --with-client-server from vim options

It keeps opening xquartz on OS X which is silly
Add a packaging task

Right now all it does is install phinze/cask, but that's an important
first step
Only run Vundle's PluginInstall post-vim install
Add virtualization role, fix go role, + cleanup

gopath is now a variable (defined in vars/main.yml), the go role no
longer uses go get to, uh, get the binaries - instead it git clones and
then installs from there. This means 2 things:

 - We only need to install (compile) when the repo changes

 - We can specify a version to install. In the case of hugo
   (spf13/hugo), that's important as HEAD is currently (?) broken

This also includes virtualization support for at least Mac OS X. It
hasn't been tested in Debian yet. That means packer, vagrant,
virtualbox, etc. are all included.
Update vimrc.d dotfiles
Remove languages from site.yml, add languages role
