GDScript (Godot Scripting Language) grammar for atom.io.

Python2 is needed for node-gyp to build tree-sitter-gdscript.
macOS: comes bundled with python2, so you don't have to worry mac users.
Windows: You may not have to worry. I have prebuilt Windows binaries that language-gdscript will attempt to download. If it fails then it will fallback to trying to build manually and you'll need to have python2 installed.
