Allow standard mode to include open files at the top

[reorx]

Quick Switcher++ is a very helpful tool, it allows me to search for open editors by typing a special prefix (edt by default) in the quick switcher. But I think it’s still not very intuitive, I want the “search any file and open it” action and “search for existing open file and activate it” to be combined into one thing to use.

In this PR I add a new setting item called “Include open files”. When it’s enabled, the switcher modal shows all the open files at the top with a different color style. If the open file is chosen, make that pane active; Other suggestions behave the same as the original, opening the file in the active pane.

The CSS color styles could be removed, it's included just for a demonstration purpose.

Thanks for the careful and professional code review ☺️, I'll refine the code and give feedback this week when I got time.
