Title: Add Status bar Indicator for Overwrite mode

@larz0 for UI review.

Please notice the ability to indicate the current toggle state when changed via insert key is depending on https://github.com/marijnh/CodeMirror/commit/f9aa052 to be include. But it can be changed via clicking on the status bar item.
