Add an "evolinux-todo" role

It makes sure there is a /etc/evolinux/todo.txt where we can append 
tasks to be done manually.

It has a task to output the content of the file, for exemple at the end 
of a playbook run.

+Creates an /etc/evolinux/todo.txt file to hold information about things to do, gathered by humans or other Ansible tasks
+
+## Tasks
+
+The main tasks install the default file if missing.
+
+A separate `cat.yml` file can be imported manually in playbooks or roles to get the content of the file. Example :
+
+```
+- include_role:
+    name: evolinux-todo
+    tasks_from: cat.yml
+```
