Subject: [PATCH] Complete implementing popover system main features (#131)

* Make popover buttons open popover menus and add placeholder messages to all of them.
* Implement all directions for drawing, aligning, and edge-clamping popovers.
* Fix popovers so they are drawn outside their parent panel bounds and not clipped.
* Fix popover HTML to avoid nesting it inside a <button> element.
