source/journalist documentation

separates source and journalist user manual, updated for 0.3. updated readme.md. also updated full_install.md up the point of running the ansible-playbook. still need to merge that doc with install.md but wanted to discuss before doing so
This is not technically correct - you are calling update to get the latest package lists. "First, you need to update your package manager's package lists to be sure you get the latest version of Ansible" would be more accurate
