Add a Menu Bar to Tesseratos

[RiscadoA]

Description

Adds a menu bar plugin to Tesseratos. This plugin basically picks up all entities with the MenuBarItem component, and shows them in the menu bar.

Additionally, ChildOf hierarchies lead to having drop-down menus within the bar.

Check out the editor main.cpp for an example of how these entities can be created.
Down the road, we should change plugins to add their own entries there.

User interaction is handled through observers: if the user selects an item in the menu, the MenuBarSelected component is added and immediately removed. This triggers any .onAdd<MenuBarSelected> observers added by users.
