Add an option to Grouped Window List to apply regex to window names

[avylove]

When you group windows by application, you still get window name like "Google - Chromium" or "Home - Linux Mint - Vivaldi" because most browsers add their name to the window name. It's redundant because the application icon is already present and the windows are grouped by application. It would be great if one could apply a regex to remove part of the window name. The Maximus Window Title applet does something similar, but only for the active window.
