change UI element to better reflect software behavior

This is a minor UI change to the desktop VLC player. My experience is only on Mac OS X. Currently running VLC "Version 3.0.11 Vetinari (Intel 64bit)" on OSX version 10.13.6 This may affect other platforms, I do not know.

Current behavior:

The current UI has an menu element under "Window" that has the title "Playlist...". It is mapped to the keycommand alt-command-P. The current function of this command creates a window overlay showing the playlist, and [selecting the menu item again] or [pressing the keycommand again] then removes the playlist overlay.

PROBLEM:

A UX confusion arises that some users (me!) did not expect a window menu item to BOTH open and close an overlay UI element.

Usually items on OSX in the window menu open windows that are standalone windows, that the user then closes by clicking a UI element in the window. (ie :This is how the "Media Information..." menu item works" AND "Main Window...","Video Effects...", etc - ALL 8 other menu items on the window menu that refer to windows open a new window that include a clickable UI element on screen to close them.) The behavior of the "Playlist..." menu item is different, works more like a toggle, and it works very well when you know what it does!

Suggestion:

1-- Rename the "Playlist..." menu item to "Toggle Playlist" (there may be internationalization here on the word "Toggle"?).

2-- Review what the appended "..." text mean on 8 of the 9 Window menu items. Currently it doesn't seem to mean anything relevant to the UI behavior. It seems correlated to if there is a keycommand assigned, so the "..." doesn't seem add anything useful. Suggestion: Eliminate the "..." text if it's not required or useful.
