adding a slide_obj in rust

Browse source 
This object is still unfinished, but it will later serve as our main
object to connect to for the slides that are shown on screen. All of
this needed some heavy tweaking and I still need to learn more about
rust, but the beginnings are there and it will be worth it to have the
safety and speed that rust provides
