Lists need some conceptual changes

[Jatoxo]

For whatever reason, I thought it would be a genius idea if all objects that wanted to be displayed in a list inherited from a base ListItem class, that defines everything needed for something to be a list item. I didn't realize that this basically meant every object that I want to have represented in a list needs to be initialized.
So, making a list of programs will actually initialize every single program. Given that we're working in a performance-critical environment with very limited resources, this idea was quite brilliant.

I only noticed this flaw until a program was actually leaking memory when it was being initialized, resulting in the program list eventually crashing.

So yea, change that
