Listening to events from all CodeMirror instances

See original GitHub issue

CodeMirror very usefully provides CodeMirror.defaults to set global defaults. I think it would be useful if there was likewise some way to specify default event handlers, or event handlers on a global bus.

If you want to write a beforeChange handler that works on all CodeMirror editors on your website, right now you have to carefully make sure you attach the handler to each instance as it is created.

CodeMirror.defineInitHook(func: function) If your extension just needs to run some code whenever a CodeMirror instance is initialized, use > CodeMirror.defineInitHook. Give it a function as its only argument, and from then on, that > function will be called (with the instance as argument) whenever a new CodeMirror instance is initialized.

god, nevermind, why am I so bad at this
