Add GDScript and Godot GLSL languages

[jmb462]

GDScript is the Godot Engine defaut scripting language.
Godot GLSL is the Godot shader language.

The colors are the same as in the godot editor. Need a dark blue background as in the godot editor.

Thanks for starting on this! I'm trying to setup syntax highlighting for snopekgames.com where I write about using the Godot engine.

I tested for GDScript, and the colors do seem to match the Godot editor, however, they are totally unreadable with a light colored background. Since GeSHi is frequently used on websites with both light and dark colored backgrounds, it'd be nice to use a color scheme that works for both.

I'm going to play around with some of the themes from https://github.com/godotengine/godot-syntax-themes and see if I can find a variation that works...

Thanks, I agree with you, my goal was to reproduce the colors in Godot Editor and only deals with the Godot blue background.
Hope you can improve that point.
