Subject: [PATCH] wx: Overload `OSXIsGUIApplication` with our own check

Some macOS apps only run in the background and thus have no GUI. Some
apps only live in the "menu bar" (top-right corner) and thus don't have
the traditional GUI either. In both cases, we don't want the application
to show up in the Dock (and thus show up when switching apps with
cmd+tab, etc)

A standard way to do this to set `LSUIElement` to `true`. See:
