configitems: issue a devel warning when overriding default config If the option is registered, there is already a default value available and passing a new one is at best redundant. So we issue a deprecation warning in this case. (note: there will be case were the default value will not be as simple as what is currently possible. We'll upgrade the configitems code to handle them in time.)
