Merge refactored roles

I am such git newb. Somehow managed to rebase *and* merge.
So, I use handlers to ensure ordering. I want the ownership/permissions enforced, and doing as a handler allows it to run *after* any other tasks in the playbook have touched the contents of those directories. This means a) other tasks don't actually need to worry about permissions and b) if they do the wrong ones, it will be fixed later.

The reason for a separate tasks to trigger them is that it made understanding the ansible logs clearer. I orginally had them notifying from the previous task with changed_when: True, but that made it look like it was touching all the dirs every run in the logs, when in reality it wasn't. So the separate tasks cleans that up.
