feat(status.bar): show line and col number

Status bar is not fired when your cursor is not in the range, but if you disable the highlight you won't see the range. Now status bar fire on whole line and will show line and col number.

* Fire the status bas on the whole line, not only the range
* Show line number, and column if available
