* msgcat.n: Added docs for new behavior from patch in [Bug: 4158].
* msgcat.test: Added tests for new behavior from patch in [Bug: 4158]. * msgcat.tcl: Applied patch from [Bug: 4158], which enables msgcat::mc to search the entire namespace ancestry chain for message translations (ie, first it checks the current namespace, then the parent, then the parent's parent, etc). Also allows the specification of additional args for msgcat::mc; if extra args are given, the [format] command is used to substitute the additional args in the translated message.
