Make sure we're installing Ansible on targets
Make sure go install also gets the deps
Add some PHP, some more Debian apps (spotify)
Add a better vim compilation process for Debian

Apparently we need to compile literally everything all the time, so we
might as well do it for Debian too. This also compiles and installs
luajit by hand because it's easier than using the apt version. I'll
probably move the luajit stuff out to a separate playbook soon.
