Inline Edit: Display cursor position in bottom left

Some editors (e.g. Eclipse) display the cursor position
in the bottom of the view. This helps to identify a specific
line or column during editing.

Include an Unsaved marker to help identify the file has
dirty changes that are not yet at the server.
