A simple .gitignore for the Godot game engine.

• Template: .gitignore example from godot demo project.

@BastiaanOlij @akien-mga (who wrote the linked gitignore) - anything to add here?

[akien-mga]

Seems fine, though should # System/tool-specific ignores be part of the Godot .gitignore? Those are not Godot-related, just standard files produced by users' file managers and IDEs.

@akien-mga good point, and yes, this should be Godot-specific rules.

This isn't specific to Godot - could you please remove it?

@fahall thanks!
