Configurable friction, dynamic max-speed, and character rotation!

• Support for rotating the character animation to match the surface slope at the grab point.
• A system for annotating surfaces by drawing marks on tile-maps in Godot's scene editor.
• Support for configurable friction per tile.
• Support for configurable max-speed per tile.
• Support for collinear neighbor surfaces.
• Support for character categories.
• Support for backtracking when overshooting the target on slippery surfaces.

Oddly-shaped surfaces, and navigation-interruption resolution!

Some highlights:

• Add support for oddly-shaped and single-vertex surfaces.
• Add more-robust navigation-interruption resolution.
• Add navigation is-stuck detection.
• Improve annotation renderings.
• Improve documentation.

Lots of improvements!

Many things have been added and fixed since v0.4.0.

Initial submission for Godot Asset Library

The framework is in a relatively stable state at this point.

I have submitted this snapshot to the Godot Asset Library.
