Added cinnamon package install

Followed instructions from http://ubuntuportal.com/2014/05/how-to-install-cinnamon-2-2-in-ubuntu-14-04-lts.html
Fixed template name in map.jinja
Grain matches Debian, not Ubuntu
Must skip verification on linuxmint-keyring
Must update apt after installing the keyring, before cinnamon
Merge pull request #1 from matthew-parlette/cinnamon-install
