feat: change default of item.users to ALL
feat: change default of item.users to ALL

Merge branch 'master' of https://github.com/Marnijt/ansible-sudo into develop
In the documentation found in the /etc/sudoers configuration file it seems that (ALL) is somewhat the default. So i changed the template to reflect that.

Closes #7
BREAKING CHANGE: unspecified item.users has changed from `""` to `ALL`
