In `Edit=>Preferences=>Editor.Features`, I added a checkbox "Comment Blank Line(s)" for issue #2239.

When this option is turned on and when commenting (`Edit=>Format=>Comment Line(s)`) or toggling comments (`Ctrl+E`), blank (empty) line(s) will also be commented.

For example, if you comment this code...

```Ruby puts <<EOD

EOD ```

..., it will do this:

```Ruby # puts <<EOD # # EOD ```

It should work for Comment, Uncomment, and Toggle. By default, it is off/false.

If this merge is accepted, `doc/geany.html` and the screenshot in this HTML file will need to be updated.
