Set window class name (xclass) in test/editor

Browse Source 
... to avoid side effects under Windows where the default would
prevent entering emoji's with the emoji palette if the WNDCLASS
begins with "edit" (conflict with a system WNDCLASS).

This is also documented in the respective tutorial chapter.

Note: setting the xclass() of the window is not required but it is considered
good style. In this case it works around a known side effect under \b Windows
where leaving the default ("editor.exe") would prevent entering emojis with
the emoji palette. You can ignore this for now in this tutorial.
Passing `argc` and `argv` to `Fl_Double_Window::show()` allows FLTK to parse
command line options, providing the user with the ability to change the
color or graphical scheme of the editor at launch time.
