Use .godot as file extension for project files.

Now project files don't have to be named "godot.cfg" anymore, they can have any name so as long as it ends with *.godot.
Also godot will automatically start the editor now if launched with a project file as an argument.
This allows for double-clicking of projects to open them :)

Code-wise this should be complete, but there's still work to do:

- Make a nice icon for godot projects.
- Work on installers/packaging -> register the extension and icon with godot.
- Update the 2.1 to 3.0 exporter.

Tested on linux and windows so far.
