Godot: Add a flag to create a project from the CLI

[rcorre]

Godot version:

3.0.6

OS/device including version:

Linux

Issue description:

Could the godot CLI have a -i/--init flag that creates a new project at the provided path?

I often spin up new projects in /tmp to just quickly test things out, and I find the current process a little clumsy. In particular, regardless of where I start godot from, the project path always defaults to $HOME, so I have to navigate through a file dialog when I already had a shell open exactly where I wanted a new project.

I realize I could probably create a script to copy a skeleton dir containing project.godot, default_env.tres, ect. to a new directory and start the editory, but this would have to be kept up-to-date with the skeleton on master

So far, I have initialized many projects using touch project.godot. It doesn't generate default environment, audiobus, and icon, but gets the job done.

That being said, such an option would be nice!
