Userland: Add GUI::Window::add_menu() and use it everywhere
...
Applications previously had to create a GUI::Menubar object, add menus
to it, and then call GUI::Window::set_menubar().
This patch introduces GUI::Window::add_menu() which creates the menubar
automatically and adds items to it. Application code becomes slightly
simpler as a result. :^)

Mandelbrot: Export images in a fixed resolution
...
This makes the exported image independent from the current window size
and just always exports it at 1920x1080.

Mandelbrot: Keep the aspect ratio when (re-)sizing the window
...
Previously the initial aspect ratio was incorrect and there was
nothing to ensure that the aspect ratio is kept when resizing the
window.

Mandelbrot: Add support for exporting the current image
...
Unfortunately this means unveil() won't work - at least until we get
something like FilePickerServer.

Mandelbrot: Implement color smoothing with gradients

This removes the color banding that happens for some of the
"outer" areas which all have the same iteration count.

Mandelbrot: Maintain aspect ratio when selecting a region
...
This makes sure the aspect ratio of the widget and the selection
match. Otherwise you'd end up with distorted images when zooming
in.

Demos: Add Mandelbrot demo
...
This adds a very rudimentary Mandelbrot viewer. It supports zooming
and pretty much nothing else. Not even color smoothing or super
sampling.
