Warn about .py/.json collisions in config...

Warn about .py/.json collisions in config when two versions of the config file set the same value, warn about clobbering, with a message, such as: ``` [TerminalIPythonApp] WARNING | Collisions detected in ipython_config.py and ipython_config.json config files. ipython_config.json has higher priority: { "Klass": { "trait": "'python' ignored, using 'json'" } } ``` In anticipation of more machine-written .json config
