TODO:

1. Write a new selection system. Godot's built-in RichTextLabel selection is limited by the node's boundaries. In normal web, holding click and dragging your mouse across the screen will select text across multiple nodes. Godot doesn't have a "set_selected_text" property, despite having one for "get_selected_text".
2. Right-click Dropdown for basic text operations (Copy, Paste, Cut). Download options for images
3. Select-all CTRL+A shortcut
4. Scrolling in the website container
5. Store tab containers so switching tabs won't erase previous tab.
6. GIF support
7. Video support via GDE GoZen

Issues:

1. < br /> counts as 1 element in WebsiteContainer, therefore despite being (0,0) in size, it counts as double in spacing.
