This patch adds a visibility state to GUI::Action. All actions default to being visible. When invisible, they do not show up in toolbars on menus (and importantly, they don't occupy any space). This can be used to hide/show context-sensitive actions dynamically without rebuilding menus and toolbars. Thanks to Tim Slater for assuming that action visibility was a thing, which gave me a reason to implement it! :^)
