Helper scripts to add simple responsive design to Godot

This may be discontinued depending on how well Godot 4 handles UI elements, and largely based on issues that have been worked around in the passed.

Current issues to be addressed.

• Font resizing based on resolution of screen or window (most likely window)
• UI element animations that are based on cords.
• automatically replace ui elements with more suitable ones based on window size.

General concept.
