Upper Left Buttons not Disabled while Main Menu is Open

[maxpetul]

While in game, if you click the upper-left main menu button repeatedly without closing the menu, multiple main menus will be created and opened next to one another. Similarly you can click to open the advisor screen while the main menu is open.

I see that we're reimplementing Popup which I assume is for the custom background. Godot's Popup is modal by default with multiple display options, and may be better to inherit from than TextureRect.

Well, the original reason we were "reimplementing" popup was that I didn't realize Godot had a built-in popup when I first decided to add a popup. But yes, the challenge with moving to the standard one at this point would be the style, and that some of them (such as Build City) are semi-custom in functionality.

I haven't examined the main menu one up close yet.
