Redesign Teta - version 0.8.4

I redesigned Teta.so for its version 0.8.4 (Beta). Let's see a preview of some of the new features.

I have introduced a merger between the 'Pages' and 'Page Status' menus to customize and control the states and parameters of each page directly from one panel.

At the top, you can switch between versions directly from the editor, saving a new version whenever you want.

I also updated the right bar, with new controls, icons, and drag-and-drop capabilities within the widget hierarchy.

We will see a new top bar with shortcuts to new nodes.
