In order to make this work, I had to determine in rust which were html
and essentially not call the change_slide function and instead call
the reveal_next/previous functions and then tweak it from there.
This is waiting till service_item_model.rs is the model actually used
for ServiceList. Right now we are still using C++ so once that
switches, we can add it in service_item_model.
This way we don't add anymore C++ code that we are likely to throw away.
This required switching from a QML Window to a QQuickView in C++. I
want to try to eventually subclass that in Rust, but for now it works.
I'll have to still tinker with this to find out how to specifically
set the screen in certain environments, but for now the user will need
to move the window on their own.
This add looping primarily for videos but I've added in the groundwork
for looping through any kind of slide. This obviously will be
implemented differently for each type of slide, but this way the
groundwork is done already.
