All resoures now use the `state` member to describe their internal
state. This includes servers, services and monitors. This means that the
`status` keyword can be reserved for something else and it can be removed
until it is needed again.
Changed the module maturity field to `maturity` to better describe its
purpose.
Added usage instructions for all commands. If the generated usage is used
with the `pkg` packager, it will contain generated script names which are
confusing.
