Todo - Deployment Settings

Some todo (deployment_setting) in cms, project and inv.
Meaning: even if there was a deployment setting for that - there are simply too many fields to always remember that there is one for this particular field out of all fields, so people would just apply the usual pattern and set readable/writable as needed (and that is how we describe it throughout all documentation). 

That in turn would lead to a practically ineffective deployment setting - and the intended gain of control would turn into quite the opposite.
