Title: Support YAML list of hosts in playbook.

Reading the docs, I was a bit confused as to how to specify multiple hosts/groups in a playbook. Being YAML, I assumed a normal YAML list would work:

---
- hosts: [host1, host2]

But this crashes when inventory._matches() assumes hosts is a string. This patch just checks if hosts is a list, and turns it into a string joined by ';'.
