New save TextCommand

{ "keys": ["ctrl+s"], "command": "save_with_comments" }

If there are any comments, Ctrl-S will save them, save the file, then re-load the comments. Otherwise, it just saves the file as normal (calling the usual 'save' command).

But, of course, you might choose to use a different key-binding.

When you open a file you will still need to use the comments' 'load' command to load previous comments.
