Update project to follow GDScript guidelines closer

Used `var variable := 0.0` as discussed in the Godot issue, instead of
`var variable: = 0.0`.

Mostly these are minor/cosmetic changes, but I've also reorganized the
folder structure (naming of folders) to reflect our guidelines, plus
made some minor changes to the demo codes. Still work in progress.
