Win and Linux Window Menu Issues

[BurningSands70]

mainWindow.removeMenu() seems to work to remove the window menu in Windows, but it does not work on Linux.

mainWindow.setMenuBarVisibility(false) seems to work on Linux (with Electron 3.x.x), but was not tested on Windows.

OSX doesn't have this issue at all
